A Zero Turn Kill, abbreviated ZTK, is one of the rarest outcomes of a Duel. To achieve a Zero Turn Kill, as per its name, a player must win the Duel without ever having a turn; this generally requires that the opponent go first and the player win during the opponent's first turn. All ZTKs require a great deal of luck, and almost always rely heavily on the opponent's actions.
Known methods to achieve a ZTK are:
- Drawing all five pieces of "Exodia" in the initial draw or during the opponent's first turn
- Having the opponent send three copies of "Jackpot 7" to your Graveyard during their first turn
- Using the last effect of "Gorz the Emissary of Darkness" in a very specific situation
- Activating Trap Cards after the player's "Makyura the Destructor" is sent to the Graveyard during their opponent's first turn, in various situations (Traditional Format only)
- Using the effect of "Infernity Des Gunman" in an extremely specific situation (Tag Force 5 only)
- Various methods involving the opponent having more than one turn before the player starts their first turn, through the Heads effect of "Arcana Force XXI - The World".
It is also possible for the opponent to lose on purpose using their own cards or surrender during their first turn.
- The chance of drawing all five pieces of "Exodia" on the initial draw of five cards, assuming the player is using the minimum of 40 cards in their Deck, is 1 in 658,008.
- In casual play, if the banlist were to be ignored and 3 copies of every card were allowed regardless of their status on the Forbidden and Limited lists, the chance would be about 1 in ~2,708.
- Outside of the initial draw, this ZTK can also occur if the opponent activates effects that allow you to draw cards during their first turn, such as "Cup of Ace".
- While ZTKs almost always require at least the opponent to start their turn, this ZTK can notably be considered the only 'true' Zero Turn Kill since it can be pulled off before either player has started their turn (thus achieving victory in a total of 0 turns for both players, not just 0 turns for the winning player).
Jackpot 7 ZTK
- There are several ways for your opponent to unintentionally send 3 copies of your "Jackpot 7" to the Graveyard during their first turn, at which point the effect of "Jackpot 7" will allow you to win the Duel:
- Card effects like "Hand Destruction" and especially "Card Destruction" (OCG or TCG Traditional Format only) can cause you to discard one or multiple copies of "Jackpot 7" from your hand to the Graveyard. You can give your opponent these two discarders using "Exchange", or better, "Present Exchange".
- If your opponent Sets a monster like "Needle Worm" or "Morphing Jar" (OCG/TCG Traditional Format), then activates "Book of Taiyou" to flip that monster, the monster's effect can cause you to discard one or multiple copies of "Jackpot 7" from your hand or Deck to the Graveyard. This is especially probable if your opponent attempts an Empty Jar FTK.
Gorz the Emissary of Darkness ZTK
- You must have "Gorz" in your hand during your opponent's first turn.
- First, your opponent must play a card that causes their Life Points to be lower than yours, such as "A Hero Lives".
- Next, they must activate an effect that inflicts damage equal to or greater than their Life Points but lower than yours. Using the above "A Hero Lives" as an example, they must activate an effect that inflicts at least 4000 damage but less than 8000 damage (for example, the effect of "Dice Jar"). Note that for the ZTK to work, this effect damage must be done as part of a single effect, not multiple consecutive effects akin to a Burn Deck.
- At this point, you can activate the last effect of the "Gorz" in your hand to Special Summon it and inflict the same amount of damage to your opponent, thus winning the Duel before starting your turn.
- This is notably the only known ZTK to require neither a Forbidden card nor an alternate win condition to pull off.
Makyura the Destructor ZTKs (Traditional Format Only)
- Your opponent must send a "Makyura the Destructor" to your Graveyard with a card like "Dark World Dealings" during their first turn. Afterward, you can activate Trap Cards from your hand in such a way as to win the Duel:
- Play "Bad Reaction to Simochi" and three "Gift Cards".
- If your opponent Summons a monster with at least 4000 ATK, such as "Malefic Cyber End Dragon", activate "Ring of Destruction" and "Barrel Behind the Door" to inflict 8000 damage.
- If your opponent heavily mills your Deck enough (such as if they are attempting an Empty Jar FTK), activate multiple copies of "Blasting the Ruins".
- Depending on what your opponent does during their turn, other card combinations may also be possible, although unlikely (such as activating "The Gift of Greed" should your opponent draw at least 33 cards in their first turn, which can be pulled off in certain Traditional Format FTK builds).
Infernity Des Gunman ZTK (Tag Force 5 Only)
- You must have an "Infernity Des Gunman" in your hand during the opponent's first turn.
- Your opponent must lower their own Life Points to 2000 or below, and also must cause you to discard all the cards in your hand. (One way to pull off the latter is through the effect of "Sky Scourge Norleras", perhaps combined with "Phantom of Chaos".) At this point, "Infernity Des Gunman" will be in your Graveyard.
- Finally, they must activate a card or effect that inflicts effect damage. At this time, banish "Infernity Des Gunman" from your Graveyard and activate its effect. Your opponent must choose to apply its optional effect and the top card of your Deck must be a Spell or Trap Card. "Infernity Des Gunman" will inflict 2000 damage to your opponent and cause you to win the Duel.
Skipping the player's first turn
If the opponent is able to Summon "Arcana Force XXI - The World" on their first turn and successfully activate its Heads effect, then they will be able to have two or more turns before the player has started their first turn. This opens up additional ZTK possibilities:
- If you are able to control a monster before your first turn (such as through the effect of "Despair from the Dark" or "Dandylion", or if the opponent uses a card like "Ojama Trio" or "Shien's Spy"), and if your opponent attacks with "Galaxy-Eyes Photon Dragon" and chooses to apply its optional effect, then you can discard "Dimension Wanderer" from your hand to inflict 3000 damage to your opponent. If your opponent had 3000 Life Points or fewer at the time of attacking, then this will win the Duel before you start your first turn, achieving a Zero Turn Kill. (Such a situation would not normally happen without the effect of "The World", because the opponent must enter their Battle Phase, which would not normally occur before the player's first turn.)
- If your opponent can pull off a World Lock to continuously skip your turns, then it is possible for you to use the effect of "Makyura the Destructor" to activate "Destiny Board", and win over the span of four of your opponent's turns while never starting your own. (Traditional Format only)
In the anime
- In Yu-Gi-Oh! - Episode 098 from the Virtual World arc, a simulated Duel was shown where a simulation of Kaiba Summoned "Blue-Eyes Ultimate Dragon" on his first turn, then used its Deck Master ability to attack directly in an FTK attempt. However, his simulation opponent used its own Deck Master ability, allowing it to pay 1000 Life Points to destroy an attacking monster. As the simulation Kaiba's Deck Master was destroyed, he lost the Duel during his own first turn.
- In Yu-Gi-Oh! GX - Episode 084, Sartorius used the effect of "Intervention of Fate", discarding it when his opponent Prince Ojin Summoned "Satellite Base" in order to activate "Ace of Sword" against Ojin's "Satellite Cannon", which had been boosted to 4000 ATK. This inflicted 4000 damage to Ojin on his own turn, winning the Duel. This was the only instance where the term "Zero Turn Kill" was explicitly mentioned.
- Notably, Prince Ojin had two turns while Sartorius had none, thanks to Ojin's "Mischief of the Time Goddess" skipping Sartorius's first turn (in the same vein as "The World" noted above).
- In Yu-Gi-Oh! 5D's - Episode 091, Kalin Kessler could theoretically have pulled off an ZTK against Lawton using "Infernity Des Gunman", if "Infernity Climber" had been in Kalin's Graveyard at the time (it is unknown whether "Climber" was sent to the Graveyard during the first turn or later in the Duel). Lawton foiled the ZTK by opting not to apply "Infernity Des Gunman's" optional effect. (Note that "Infernity Des Gunman's" effect is slightly different in the anime than in Tag Force 5.)
- In Yu-Gi-Oh! ZEXAL - Episode 138, Don Thousand pulled off an outcome close to an ZTK against Mizar, activating "Numeron Network" from his hand at the start of Mizar's turn through its effect, then using "Numeron Network" to activate "Numeron Spell Revision" from his Deck, which in turn forced Mizar to activate "Card of the Dragon King". This was not a true ZTK however, as Don Thousand did have a turn before winning (although he passed that turn, doing absolutely nothing).
