A friend of mine built a casual omniscience deck a few weeks ago that tried to resolve the enchantment, then draw the deck using reforge the souls and thunderous wrath the opponent 4 times. I changed 25ish cards and came to this. I haven't tested it much, but when I have it wins on the spot every game you resolve omniscience. The deck can easily support a splash color for a thragtusk/huntmaster of the fells plan in the sideboard or even maindeck. Black could be a splash for duress out of the board, but negate and dispel do similar enough things that I think that's a worse option.
