Worldquake Giant

At the beginning of combat on your turn, you
may sacrifice a land or creature. If a land is
sacrificed this way, exile the top two cards of your
library. You may play those cards this turn. If a
creature is sacrificed this way, Worldquake Giant
deals damage to any target equal to your devotion
to red.
