It uses Lich and a combination of other cards which tend to vary in order to go off like the Turboland deck (if you recall that one--it was powered by Exploration and Horn of Greed), but typically faster and more broken. Optimally, it killed by getting the combination of Fastbond, Glacial Chasm, Overgrown Estate, and Lich. Fastbond meant it could play every land in its hand. Glacial Chasm meant it didn't take any damage from Fastbond (or any other cards), and Overgrown Estate allowed it to sacrifice each land after using it for mana in order to draw more cards with Lich, some of which would be lands, which could be played with Fastbond and then sacrificed to Overgrown Estate to draw cards with Lich, and so on...
