From Across the Sea

Whenever an opponent casts a creature spell, reveal cards from the top of your library until you find a noncreature, nonartifact spell. Put that card into your hand and the rest on the bottom of your library in a random order.
"Balloons the size of dragons, giants made of metal... For god's sake, they shot balls of fire across the horizon. I don't know who they are, but I'm preparing for war."
