Bedlam Reveler 6 R R
Creature - Devil Horror
Bedlam Reveler costs 1 less to cast for each instant or sorcery card in your graveyard
When Bedlam Reveler enters the battlefield, discard your hand and draw 3 cards
Let's assume this costs RR. Let's also assume this draws 3 cards. Under those premises, it's a damn good card, awesome in fact.
Can we throw this in any existent deck? Maybe UR delver, but probably this card demands something pretty aggressive, with few countermagic (you don't want to put the fows in the grave for fun)
While it does not have evasion (would have been broken), i like it a lot. Add bolts, maybe chain lightning, price of progress or other direct damage spells, and this is a devastating late game card.
