Raum, Fist of Rakdos

Flying, trample
When Raum, Fist of Rakdos enters the
battlefield, you may search your library and/or graveyard for a card named Rakdos, the Showstopper, reveal it, then put it into your
hand. If you searched your library this way,
shuffle it.
"I serve Rakdos. I fight for Rakdos. I will die in time
for Rakdos."
