Emrys, King of Cats

When Emrys, King of Cats enters the battlefield, gain control of target Cat creature an opponent controls until end of turn. That creature gains haste until end of turn.

At the beginning of your upkeep, if you control three or more Cat creatures, you may return a Cat creature from your graveyard to the battlefield.

"Emrys rules with an iron paw. Just don’t try to touch his favorite chair—or you might lose a finger."
