, : Each player puts the top three cards of their library into their graveyard. Exile up to two creature cards put into graveyards this way. Create an X/X blue Zombie creature token, where X is the total power of the cards exiled this way.
11/7/2014 “Exiled this way” refers to the exile instruction that’s part of the ability’s effect. If the cards each player would put into their graveyard are exiled because of a replacement effect, those cards won’t be in the graveyards to be exiled by the next part of the ability. In this case, the value of X will be 0. You’ll put a 0/0 token onto the battlefield, then that token will die and subsequently cease to exist (unless something else raises its toughness above 0).
