A First Turn Kill is similar to a One Turn Kill, but this is pulled off in a player's first turn, even the first turn of the Duel. New "First Turn Kill" and "One Turn Kill" decks are available after the release of "Cyber Valley" in the booster Phantom Darkness. New tactics like Banisher Mill innovate in the field of FTK's with complex new strategies. These kind of decks are considered "broken" and frowned upon by many duelists because of the absence of skill involved with the duels themselves, especially at a high rate of success. First, FTK users either have to hope they go first and kill their opponent that first turn or they hope they survive and try again. This relies a lot on luck rather than skill on the FTK user. Second, it completely ignores both the opponent's deck and the Side Deck. They can have the best deck in the metagame or all the tech cards to counter the FTK, but the chances of success for the opponent is still slim.
