Ageless Entity - 3GG Creature - Elemental (R) Whenever you gain life, put that many +1/+1 counters on Ageless Entity. 4/4 (Above from Darksteel Spoiler at www.mtgnews.com) This is probably the place we want to start. Next, we want efficient Life Gain cards. Examples are [card]Heroes Reunion[/card] and: Nourish - GG Instant (U) You gain 6 life. (Again from Darksteel Spoiler) Now Heroes Reunion basically reads: GW: Put 7 +1/+1 counters on Ageless Entity. So can we think of more cards or even a real Life Gain deck that would be viable?
