cast this card, draw a card. If its the 3rd, draw a
card and return target creature to its owners

draw that many cards. If it's the 5th time, draw 7
cards and you have no maximum handsize for
the rest of the game. Then if it's the 6th time,
return all nonland permanents your opponents
control to their owners hand. Shuffle Time and
