Theme: Gaining and spending life.

Gameplan: Fight opponents with lifelinkers, extort when possible, spend life on card draw or making giant Phyrexian Processor tokens.  If life gets high enough, go for the cheap win with Felidar Sovereign or Test of Endurance.  Otherwise, there's always the other cheap win of Exquisite Blood + either Vizkopa Guildmage or Sanguine Bond.  Casting Ad Nauseam on an opponent's end step is a strong way to dig out win conditions, and the life loss can potentially be recouped with Children of Korlis or Martyr of Sands.

Strengths:  Can absorb beatings that would obliterate decks without lifegain.  Good amount of card draw.

Weaknesses: A little light on creatures & threat density.  Opponents often reduce the benefits of lifegain by being extra-aggressive in response.
