The Extra Deck (Japanese: エクストラデッキ Ekusutora Dekki; usually abbreviated ＥＸ (エクストラ) デッキ since Code of the Duelist), formerly known as the Fusion Deck (融 (ゆう) 合 (ごう) デッキ Yūgō Dekki), is a Deck where Fusion, Synchro, Xyz, and Link Monsters (as well as Pendulum Monsters that would otherwise have been sent from the field to the Graveyard) are stored during a Duel.

Mechanics

The Extra Deck is separate from the Main Deck, and contains combinations of Fusion, Synchro, Xyz, and Link Monsters. During the game, it is placed face-down in the Extra Deck Zone, and a player can Special Summon Monsters included in there.

Construction

The Extra Deck has a maximum size of 15 cards (including all Fusion, Synchro, Xyz, and Link Monsters combined). Per the "Maximum of 3 Rule", during Deck construction there can be at most 3 cards with the same name in a player's Main Deck, Extra Deck and Side Deck (combined). Usage of Extra Deck is not mandatory by rule.

Gameplay

During a Duel, players can Special Summon Monsters from the Extra Deck through Fusion Summon, Synchro Summon, Xyz Summon, Pendulum Summon, Link Summon, or any other cards that Special Summons from Extra Deck. It is not necessary to shuffle the Extra Deck, even when a card specifies that the card would be shuffled into the Deck.

If a Fusion Monster, Synchro Monster, Xyz Monster, or Link Monster would be returned to the hand or Main Deck, it is instead returned to the Extra Deck (face-down), since Fusion Monsters, Synchro Monsters, Xyz Monsters, and Link Monsters cannot exist in the hand or the Main Deck.

Pendulum Monsters

Unlike other Monster cards, Pendulum Monsters that would be sent to the Graveyard from the field are placed face-up into the Extra Deck.

Pendulum Monsters placed face-up in the Extra Deck during a Duel can cause the total size of the Extra Deck to exceed the maximum size permitted during Deck construction.

Extra Monster Zone

Link Monsters and Pendulum Monsters that are Special Summoned from the Extra Deck must be Special Summoned to an Extra Monster Zone or a Main Monster Zone pointed to by a Link Monster.

Fusion, Synchro and Xyz Monsters that are Special Summoned from Extra Deck may be Special Summoned to either Extra Monster Zone or Main Monster Zone.

In case of Fusion Pendulum, Synchro Pendulum and Xyz Pendulum Monsters, they can be Fusion/Synchro/Xyz Summoned to any zone from face-down. But when Pendulum Summoning them from face-up, they must be Summoned to an Extra Monster Zone or a Main Monster Zone pointed to by a Link Monster.

When Special Summoning from the Graveyard or banished, an Extra Deck Monster must be Summoned to a Main Monster Zone.

Knowledge

The face-down contents of the Extra Deck are not public knowledge, so a player may not look through face-down cards in their opponent's Extra Deck.

The face-up cards in the Extra Deck are public knowledge, so either player may look through them at any time.

The number of cards in the Extra Deck is public knowledge.

Anime and manga

Limits on the number of cards that are stored in the Extra Deck in the anime and manga are not yet determined. It is also not clear at all times of the series if the Extra Deck even exists; in many early Duels, the players seem to simply fuse monsters without ever apparently pulling the Fusion Monster card from anywhere.

It is also not clear at all times where the Extra Deck is kept:

• In Yu-Gi-Oh! GX, Fusion Monster Cards are not seen to be played from anywhere, but the Fusion Monster Card is present on the Duel Disk after it is Summoned.
  • Zane Truesdale's Fusion Deck is shown to be mixed in with his Main Deck; on one occasion, he searches his Main Deck for "Chimeratech Overdragon" when Fusion Summoning it.
• In Yu-Gi-Oh! 5D's, Akiza Izinski can clearly be seen to have an Extra Deck Zone built into her Duel Disk. Yusei Fudo and Jack Atlas's Extra Decks are stored with their Main Decks; both are shown adding "Stardust Dragon" to their Main Decks before a Duel.
• In Yu-Gi-Oh! ZEXAL, the Extra Deck is stored in a box on the Duelist's belt.
• In Yu-Gi-Oh! ARC-V, Duel Disks are specifically shown to have an Extra Deck Zone compartment.
  • In Episode 134, there are 15 cards face-down behind "Odd-Eyes Pendulum Dragon" and "Performapal Coin Dragon". This number matches the Extra Deck limit in the TCG and OCG.
• In Yu-Gi-Oh! VRAINS, the Extra Deck is not specifically shown due to the streamlining of most LINK VRAINS Duel Disks. However, if the Duelist is using a "Storm Access"-like Skill, cards can be randomly added to it from Data Storms and formed into actual cards in the real world.
