Grand Admiral Thrawn

Thank You for Your Assistance - Whenever another nonartifact creature dies, return it to the battlefield under your control face down and tapped. It's a 2/2 Sentry Droid artifact creature.

The Cost of That Failure - At the beginning of your end step, each opponent faces a villainous choice - Each artifact creature you control deals 1 damage
to that opponent, or you draw a card and chaos ensues.
