During your opponent's combat phase, you may
sacrifice a non-token creature you control. If you do, prevent all damage that would be dealt to you by a target attacking creature that opponent controls. During your next turn, Kuruk gets +X/+X until end of turn, where X is the attacking creature's power. Kuruk also gains trample until end of turn.

destiny of the world."
