Corpse Cleaner 2BB
Creature - Ogre Rogue (Mythic)
Whenever another nontoken creature you control dies, Corpse Cleaner connives.
When Corpse Cleaner dies, return another target non-Rogue creature card with less or equal power than Corpse Cleaner from your graveyard to the battlefield.
While we have all these incidental graveyard-matters cards for Connive, we don't have more tangible rewards. This one lets you reanimate one of them back eventually. Attaching it to a death trigger means you get twice as many choices, and stuffing your graveyard twice as fast. You can even just play him for the card filtering in sacrifice-heavy decks.
