I could maybe see this being played as a two-of in the 4- and 5-colorc control decks in Modern, and it may even break into the multicolored decks in Pioneer as well
I know some will say that Archfiend Black Skull Dragon is superior to this card but I'm the kind of guy who feels you can't replace the originals, especially this one with its awesome design that few others have matched
Probably makes a difference
No costs, no questions, no mercy
Most good single-target removal exiles now, and even board wipes are getting there
Go to that combat phase and you either get the red Overrun for a great reason to attack with everything, a new hand of options, or you can pick off one of the more annoying blockers or send a Lava Axe to the face and completely change combat math
