Unwanted Rescue

Enchant creature
When enchanted creature dies, return it to the battlefield under your control. It gains "This
creature can't attack or block."
"It is difficult discerning him as he doesn't speak, or chooses not to, and refrains from physical conversation beyond simple gestures when it pleases him. He
engages in other activities on a mysterious schedule
and seems to make good use of any time I'm away or
the rare chance I may be caught sleeping."
