Legendary Creature - Vampire Assassin 

3/5 

Etrata, the Silencer can't be blocked. // Whenever Etrata deals combat damage to a player, exile target creature that player controls and put a hit counter on that card. That player loses the game if they own three or more exiled cards with hit counters on them. Etrata's owner shuffles Etrata into their library.
