NeoGoat at Cartoncito Cards: September 29 Tournament

On September 29, 2026, we had 8 players at Cartoncito Cards for 3 rounds of NeoGoat. This was a transition tournament: players could use either the August 2026 banlist or the October 2026 banlist. That gave us a chance to see decks from both lists play against each other.

Round 1: Monarch vs. Rock

Our first match was Monarch using the October banlist against Rock using the August banlist.

The Rock deck had a PACMAN-style plan, using monsters like Golem Sentry and Medusa Worm to keep removing opposing monsters. But it could hit hard too! Giant Rat brought out Enraged Muka Muka, which kept reaching around 2400–2800 ATK and dealing heavy damage.

The last duel had a really cool finish. The Rock player cleared the Monarch player's monsters, but there was still one face-down Spell or Trap to worry about.

The Rock player took the risk and summoned Megarock Dragon, banishing 4 Rock monsters from the Graveyard. That gave it 2800 ATK, and its attack went through for exactly enough damage to win the duel and the match!

Winner: Rock — August 2026 banlist.

Match 2: Dino Zombie vs. Good Stuff

Next was Dino Zombie using the August banlist against Good Stuff using the October banlist. Dino Zombie took the match, giving the August list another win in the matches covered here.

Winner: Dino Zombie — August 2026 banlist.

Final Match: Pandemonium Archfiend vs. Monarch

The final match featured Pandemonium Archfiend using the October banlist against an unexpected Monarch deck using the August banlist.

The Archfiend deck brought Mist Archfiend, a new option for October, and also played Card Destruction. The match went to three duels, with Archfiends taking it 2–1.

Winner: Pandemonium Archfiend, 2–1 — October 2026 banlist.

A Ruling to Clear Up

There was a mistake with Archfiend of Gilfer and Pandemonium. The Archfiend player used Foolish Burial to send Gilfer to the Graveyard, then used Gilfer's effect to equip it to an opponent's monster.

When that monster was destroyed by battle, the equipped Gilfer was also destroyed. The player then used Pandemonium to search for another Archfiend, thinking that Gilfer counted because it had not been destroyed by battle.

The key detail is that Gilfer counts as an Equip Spell while equipped. Pandemonium needs an Archfiend monster to be destroyed and sent to the Graveyard outside of battle. Since Gilfer was an Equip Spell when destroyed, Pandemonium could not search in this situation.

The ruling was not checked by a judge at the time, so the search went through during the match. From the next duel onward, the correct ruling will apply: an equipped Gilfer being destroyed does not give a search with Pandemonium.

NeoGoat Rulings That Are Different from Goat Format: Part 2

NeoGoat uses old Yu-Gi-Oh! cards, but we are not playing with a 2005 rulebook.

One of the basic rules of NeoGoat is pretty simple: unless the format specifically says otherwise, we use the current official Yu-Gi-Oh! rules and card rulings.

That also means NeoGoat can change without adding a single new card. If Konami changes a game mechanic or updates the ruling of an old card tomorrow, that new ruling also applies to NeoGoat.

Basically:

Old cards. Modern rules.

Most of the time this doesn't matter much. But every once in a while you get an interaction that works differently from traditional Goat Format. Some of them are pretty weird.

Here are three examples that we can reproduce directly in NeoGoat Pro.

---

1. Rivalry of Warlords Can Stop a Flip Effect

Let's start with a situation that looks completely normal.

You have Rivalry of Warlords active and control a face-up Warrior. You also have a face-down Spellcaster.

Your opponent attacks the face-down monster.

The monster still flips face-up before damage calculation. Rivalry doesn't magically stop that part of the battle. Damage calculation also happens normally.

But after damage calculation, you are now controlling two different Types. Because of Rivalry, the newly flipped Spellcaster is sent to the Graveyard.

Here is where the modern ruling matters.

If the attacked monster has a Flip Effect, or another Trigger Effect that would activate after damage calculation, it cannot activate, because Rivalry has already sent that monster to the Graveyard before it gets the chance to activate its effect on the field.

This is different from the old Goat Format interaction, where the Flip Effect could still activate.

It's a tiny rules difference, but in a format full of Flip Monsters, it can absolutely matter.

Don't believe us? You can check the official Konami ruling here . The official Q&A explains the interaction between Rivalry of Warlords, an attacked face-down monster of another Type, and its effect timing.

2. Deck Devastation Virus vs. Monsters with ? ATK

 

Now we get to the mysterious little ? printed in the ATK box of some monsters.

In old Goat rulings, monsters with ? ATK could be treated as having 0 ATK for effects like Deck Devastation Virus while they were in the hand.

That is not how the current rules handle it.

A monster with ? ATK in the hand does not have 0 ATK. Its ATK is still ?.

And "?" does not automatically mean "1500 or less."

So Deck Devastation Virus does not destroy a ? ATK monster in the hand.

But now comes the funny part.

If that monster is face-down on the field, its ATK is treated as 0 when an effect needs to check its ATK. That means Deck Devastation Virus does destroy it.

And if the monster is already face-up, you look at the ATK it actually has at that moment. If its current ATK is 1500 or less, Virus destroys it. If it is above 1500, it survives.

So the same card can survive Deck Devastation Virus in your hand and then immediately become vulnerable to it once it's sitting face-down on the field.

Yu-Gi-Oh! rulings are beautiful sometimes.

Konami's official database has a ruling using Tragoedia that explains exactly how ? ATK works in these locations: in the hand it remains ?, while a face-down copy on the field is treated as having 0 ATK when its ATK needs to be checked. You can read the official Konami ruling here .

3. Mind Control + Book of Moon Lets You Tribute the Monster

This one is probably the weirdest of the three.

Mind Control says that the monster you take cannot attack or be Tributed.

Simple enough.

So normally you can't steal your opponent's monster with Mind Control and then use that monster for something like Metamorphosis.

But under the current ruling, something strange happens if you take a face-up monster and then turn it face-down with Book of Moon.

You still keep control of that monster until the End Phase...

...but the part of Mind Control that says the monster cannot attack or be Tributed stops applying.

Yes, that means this is completely legal in NeoGoat:

Mind Control → Book of Moon → Metamorphosis

You steal the monster, Book it face-down, and then Tribute your opponent's monster for Metamorphosis.

Traditional Goat Format does not allow this.

Under the old ruling, flipping the monster face-down did not remove Mind Control's restriction. The monster still couldn't attack or be Tributed until the End Phase.

And because Yu-Gi-Oh! rulings apparently weren't weird enough already, there is another detail:

If Mind Control takes a monster that was already face-down, the restriction still applies. Even if that monster is later flipped face-up, it still cannot attack or be Tributed while Mind Control's effect is applying.

So:

• Mind Control a face-up monster → Book of Moon: you can Tribute it.
• Mind Control a monster that was already face-down: you cannot Tribute it.

Same card. Same turn. Different result depending on whether the monster was face-up when Mind Control resolved.

And yes, this one is straight from Konami too. The official Q&A specifically says that if a face-up monster taken by Mind Control is changed to face-down Defense Position, you still control it until the End Phase, but the restrictions preventing it from attacking or being Tributed are no longer applied. You can check the official Mind Control ruling here .

Why Does NeoGoat Use Modern Rulings?

NeoGoat takes the cards, pacing and deckbuilding style we like from old Yu-Gi-Oh!, but runs them using the current game engine.

That makes the format much easier to maintain.

You don't need one rulebook for regular Yu-Gi-Oh!, another one for NeoGoat, and a folder full of rulings from twenty years ago just to remember how one random interaction works.

Using modern card rulings helps NeoGoat stay compatible with platforms like Master Duel and other modern Yu-Gi-Oh! simulators, where the current rules are already built into the game. It also avoids giving judges unnecessary headaches. Most judges already work with the current rules used in Advanced and Genesys at official tournaments, so asking them to switch back and forth between modern rulings and a separate 2005-style ruleset would just create more chances for confusion and mistakes. 

If Konami fixes, changes or clarifies a ruling, NeoGoat simply moves with the game.

It can also create new interactions between old cards that didn't exist when those cards originally came out, which is honestly part of the fun.

NeoGoat isn't supposed to be Yu-Gi-Oh! frozen.

It's old-school Yu-Gi-Oh! running on a modern engine.

If Konami changes the rules tomorrow, NeoGoat changes with them.

And whenever one of those changes produces something especially weird, we'll try to reproduce it in NeoGoat Pro so everyone can actually see how it works instead of arguing about it for three hours.

Rules examples in this article reflect current Konami rulings as of September 2026.

Rallis the Star Bird Deck

 Today we bring a showcase video featuring one of the most unique strategies in the NeoGoat metagame: the Rallis the Star Bird WIND deck. This deck was posted here: https://neogoatformat.blogspot.com/2025/11/neogoat-tournament-report-november-18th.html

In the showcased duel, viewers will observe:

• How Rallis returning dodges Torrential Tribute because returning to the field is not treated as a Special Summon.

• How Rallis can attack under Messenger of Peace and increase it's attack on the damage. 

• That it increases attack also when attacked by opponent.

The NeoGoat Extra Cards List

Why It Exists?

NeoGoat’s identity is defined by a fixed historical core cardpool: all OCG cards released before Cybernetic Revolution, including:

OCG-exclusive vanillas, rituals, and non-effect fusions, Soul Taker, Magical Dimension, Shrink, Summoner Monk, Marshmallon, Shield Crush, Copycat, the Gadget trio, Castle Gate, Vampire’s Curse, Zoma the Spirit, Union Attack, and many more.

Also cards from the first 8 Structure Decks

These are permanently legal:

1. Dragon’s Roar
2. Zombie Madness
3. Blaze of Destruction
4. Fury from the Deep
5. Warrior’s Triumph
6. Spellcaster’s Judgment
7. Invincible Fortress
8. Lord of the Storm

Edit: More Structure decks may be added in the future.

This forms the Fixed Cardpool
— the historical backbone that never changes.

Where the “Extra Cards List” Comes In

Alongside the fixed cardpool, NeoGoat includes a rotating Extra Cards List — a selection of cards that originally came after CRV, or exist outside the strict historical window, but add thematic freshness.

This list is not huge, but it is purposefully diverse.

https://www.duelingbook.com/deck?id=18903725

 (This was October 2025 Extra List)

Examples from the Extra List

• E·Heroes & support: Neos, Wildheart, Bladedge, Bubbleman, Prisma, Fifth Hope, E–Emergency Call, Miracle Fusion

• Field-searchers: Harpie Queen, Warrior of Atlantis, Zeradias

• Dragons: Totem Dragon, Red-Eyes Wyvern, Paladin of Dark Dragon

• Fusion support: Overload Fusion, Fusion Recovery, Dragon's Mirror

• Spellcaster / Spell Counter tools: Dark Red Enchanter, Magical Exemplar, Magical Citadel

• Utility cards: Pulling the Rug, Radiant Mirror Force, Trojan Horse

• Normal Monster Support: Unexpected Dai, Summoner’s Art

• Extra Deck: Amulet Dragon, HERO fusions, VWXYZ, etc.

These cards enter the format only when the banlist committee allows them, and they can be rotated or removed later.

The Extra Cards List is a design tool with three goals:

1. To Add Controlled Novelty Without Power Creep

NeoGoat wants to stay 1999–2005 in spirit, not to become Edison or TeleDAD.
So instead of opening the floodgates to modern cards, the Extra List allows only certain cards. 

Examples:

• HEROes bring a new archetype without introducing broken “modern” cards like Elemental Hero - Absolute Zero or similar.

• Unexpected Dai enables vanilla-based builds, synergizing with the OCG-only Normal Monster pool.

• No new game mechanics, like tuners, gemini, psychics, etc.

This keeps creativity alive while protecting the “Goat-like” pacing.

---

2. To Temporarily Highlight Archetypes or Strategies

Every few months, the Extra List can shift to support a theme:

• A season that highlights HEROes

• A focus on Wind and Fire decks

• A Dragon season with Paladin + Ritual + Timaeus cards

• A Machine season with VWXYZ and Overload Fusion

This creates mini “format eras” that feel fresh but remain fair.

---

3. To Connect the Format to GX and Anime Series Without Breaking Goat

Many players love early GX themes (HEROes, Ancient Gear, certain field-searchers, Spell Counter cards, Dark Magician cards, VWXYZ machine fusions).
However, these cards did not exist yet in Goat Format.

The Extra List allows NeoGoat to include the early roots of these themes:

• HERO fusions are playable but not insane.

• VWXYZ is has combo material but slow enough.

• Dark Red Enchanter and Magical Exemplar introduce a “Spell Counter” sub-archetype that fits Goat pacing.

This keeps NeoGoat historically inspired, not historically frozen.

---

In conclusion

Fixed Cardpool = the foundation

The classic OCG cards define 90% of the format’s meta and gameplay.

Extra List = seasonal 

New toys. New archetypes. New ways to build decks.
Staying balanced because:

• the list is small

• cards can be removed in future updates

• high-power modern cards are never allowed

• cards are monitored in tournaments

This preserves long-term stability while enabling periodic reinvention.

Without Extra List players would mainly explore Goat, Chaos, Control, Warriors, Monarchs, Burn, and over time, exploration becomes limited.

With the Extra List the format remains far more alive.

NeoGoat rulings that differ from Goat

 In Neo Goat format some cards are more powerful than in Goat format, here we present 3 examples:

My Body as a Shield

My Body as a Shield can be activated during damage step in Neo Goat format, because it negates card activations. The rule here is that if a quick-play spell, monster effect or trap card negates card activations it can be used during damage step, for example, Stardust Dragon in Edison Format. 

Last Will

The ruling we use here is that Last Will can be activated as a normal spell card, (you can activate this spell it even if you don't have any other card), after that, you can use it's effect if a monster on your side of the field has been sent to your graveyard this turn and you can resolve the effect of your Last Will anytime during the turn, even Battle phase or End phase as you can see in the video, just not inside a chain or other action as this effect is not chainable. Also, you can use more than one Last will, in that case each one will work separatedly, you could also end your turn without using the effect even if you could.

Fox Fire

In Goat Format, if a face-down Fox Fire is attacked, its effect is not applied even though it is face-up when destroyed. But in Neo Goat it can use it's effects even if it was face-down when the attack was declared. The card text seems to specify that it should be face-up at any moment but as you can see in the video this is how it works, so it's more like a Revival Jam.

We will be posting more rulings like these in the future so players can use these cards accordingly.

What is Neo Goat Format?

 Neo Goat Format idea originated from the Master Duel Trial Event: Time Travel 2004. That event was very similar to Goat Format but it felt more balanced and it had more deck options. This exact way of playing was introduced to local store tournaments and it was very fun. The format has been gaining popularity since then.

After some months of playing there were changes made to the original banlist (for example prohibitting Change of Heart and Black Luster Soldier - Envoy of the Beginning), since this is a format never seen before it is not known what ideas people will come up with, so the banlist is subject to periodic change, around every three months) to avoid the appearance of a very dominant deck.

Because of it's origin there are many differences with respect to the original Goat format, in short this format is played as it would be played in current Yu-Gi-Oh!, except for the rule that the first player draws a card in the Draw Phase of the first turn.

1. PLAYER STARTS WITH 6 CARDS IN HAND

If you want to play this format in Master Duel or any Yu-Gi-Oh! simulator, the player who wants to go first let his opponent begin, the first turn is just skipped, and the second turn has no Battle Phase. Don't use Extra Monster Zone.

In Duelingbook or Local Tournament you just begin with 6 cards in hand.

2. NO PRIORITY

When you summon a monster with an ignition effect that is not a quick effect, the opponent can first respond to the summon. 

3. ERRATA OF THE CARDS

Allowed cards are used with their most recent errata.

Example of cards that are affected by the rule: 

Ring of Destruction, Sinister Serpent, Crush Card, Rescue Cat, Brain Control, Dark Magician of Chaos, Night Assailant, and others.

4. THERE CAN BE TWO ACTIVE FIELDS AT THE SAME TIME.

Activating a field spell card does not destroy the opponent's face-up field spell card. 

5. FUSION DECK HAS A LIMIT OF 15 CARDS AND MAIN DECK LIMIT OF 60.

6. RULING UPDATES THAT TAKE PLACE IN THE YU-GI-OH! CURRENT FORMAT ALSO ARE APPLIED IN THIS FORMAT.

Examples:

- The rule issued in 2019 that opponent doesn't have to show hand when Mnd Crush resolves.

- The rule issued in 2024 that a monster flipped face-down while equipped with Snatch Steal returns to the original owner.

- The rule that states that if a monster like Relinquished attempts to equip an opponent's monster and an effect is chained that causes Relinquished to be removed from the field or flipped face down, the monster selected by Relinquished will be sent to the Graveyard.

- The rule that you can't activate effects that search cards from the deck if there are no targets. (Reinforcements of the Army, Thunder Dragon)

- The rule that you cannot tribute summon a monster while Rivalry of Warlords is active if the type of the monster you are trying to tribute summon is not the same type as the face-up monster you control. 

[Remember that this format is played as modern Yu-Gi-Oh! with a limited banlist except for the first rule.]
