Mugoji, Hujin's Pacifier

Protection from black and from blue
Whenever one or more creatures an opponent controls dies or is put into exile, you may pay {r}{g}{w}. If you do, reveal cards from the top of
your library until you reveal a nonland permanent card. Put that card onto the battlefield, then shuffle. If a creature enters the battlefield this way, Mugoji, Hujin's Pacifier deals damage to target player or planeswalker equal to that creature's power.
