One Turn Kill

A One Turn Kill is achieved when a player wins a Duel in the space of a single turn, as soon as said player has the appropriate cards in hand and has control over the duel. This is similar to a First Turn Kill, but the latter is pulled off during the player's first turn, while an OTK can be accomplished at any point of the duel (meaning that all FTKs are OTKs, but not all OTKs are FTKs).

In one turn, all of the opponent's Life Points, which is normally assumed to be no more than 8000, must be depleted or an alternate victory condition must be fulfilled.

Significant or reliable OTKs generally consist of 4 or fewer cards, do not require the opponent to have particular cards or rely on indefinite chance, such as the effect of "Snipe Hunter".

Traditional and Advanced Formats will have very different OTK styles, owing to the allowable Card Pools. The Advanced Format banlist is updated every six months to reduce the viability of OTKs.
