Emergence

Target creature you control gains Appeal.
(At the beginning of your next end step, you may
exile that creature with an Appeal counter on it. For
as long as it remains exiled this way, you may pay {b}{b}. If you do, remove the counter, and return that creature to the battlefield under your control.)
"Death is just a life that failed to live. This way, I
give them what they never could have imagined."
