This deck is built solely to wreak havok in 4+ player games. With Bazaar Trader, you can shunt off Abyssal Persecutor to people, forcing them to find a way to get rid of it before everyone else kills them. Give someone a Lich's Mirror, and they can't die until you do - which you can ward against with Privileged Position and Platinum Angel. Chromatic Lanturn starts as early-midgame mana fixing, but you can offer it to an opponent with Bazaar Trader for a brief truce when you have no need of it. Emrakul gives a win condition and a rather powerful bargaining chip. Brooding Saurian and Homeward Path are last resorts, if you absolutely cannot live without something being destroyed.

Omniscience is in the deck because it's the last card most people would expect. I know I wouldn't.
