Camille, Sleepy Guard

Vigilance

Power nap — Whenever Camille attacks, you may exile him. If you do, return him to the battlefield tapped under your control at the beginning of your next upkeep.

Eternal Slumber — At the beginning of your end step, if Camille is tapped, exile him. You may cast him from exile for as long as you control a Swamp.

"He swore to fight until his last breath. He didn’t expect his last breath to come with a pillow."
