I know there's a rule against special victory cards but I'm going to see if I can pull this off in a likable manner.
This card is based off an anime card that let the use win if they can draw another copy of it by drawing but I'm going to change it up a bit.

Quick-Play Spell
Shuffle this card back into the deck if you activate it or draw it by effect. After activation of this effect if you draw 2 consecutive copies of this card on 2 consecutive turns you win the duel. (Only the first draw on a turn after the activation of this card is counted each turn no matter what caused the draw to occur)
The general idea here is you won't be able to win the same turn you used this effect even if you could draw the whole deck during that turn. It also means you have to find a way to stall for time and survive you opponent's turn long enough to win.
