This is pretty weak at the moment just thought it up today but {sheoldred, the whispering one} with {pardic miner} in a black red land destruction. I know it's not practical but so much lolz
You could get some decent use out of {Furnace Celebration} with this. {Pawn of Ulamog} could slowly get you some mana. {Grave Pact} or {Butcher of Malakir} if you want to wipe the board faster. Definitely a lot you could do with this!
The only issue I see is that, by the time you hard cast Sheoldred, they'll have all the mana they need. But, if you're toasting their land anyway....
