Krark, Suspicious Donator

Whenever you cast an instant or sorcery spell that affects only you or a single permanent you control, flip a coin. If you win the flip, an opponent of your choice gains control of that spell. If you lose the flip, scry X, where X is that spell’s mana value.

After you flip a coin, you may sacrifice 2 goblins. If you do, flip another coin, and ignore all but one result.
