Silzeyrakl enters the battlefield tapped
Whenever Silzeyrakl deals combat damage to a
player, exile that many cards from the top of their
library. Until end of turn you may cast up to three
spells exiled this way and you may use mana of any
color to cast them. Shuffle the rest into that player's library.
