Callidus Assassin (40K-109) is a rare creature — Human Shapeshifter Assassin from the Warhammer 40,000 Commander set. It has Flash and a Polymorphine ability that lets it enter tapped as a copy of any creature on the battlefield while gaining a triggered destroy ability tied to the copied creature's name. The card can instead enter as a standalone 3/3 if you choose not to copy anything, giving flexible roles as a disruptive or mimic creature in decks.
