Clockwerk, A Heart of Hate

Flying, Indestructible, Hexproof
When Clockwerk, A Heart of Hate enters the battlefield, exile all cards with "Cooper" in the name from the battlefield and graveyard. If 5 or more cards were exiled in this way, you get an emblem with "Whenever Clockwerk deals combat damage to
a player, that player loses the game."
If Clockwerk, A Heart of Hate would be put into a graveyard from anywhere, return it to the top of the owner's library instead.
