New Deck Ideas:
Gain control effects
Sac effects
Draw cards
Burn spells
Gain Life

Original Deck Ideas:
Kill spells with black
Burn spells with red
life drain and gain, cheap (black)
Card draw (arena, underworld connections, greed?)
Hasty trample sacrifice for cheap (just a few)
counter spells (?)

I'd say about half burn/kill spells and half drain any target?
