Gestrag, the Lightgiver

Vigilance, haste
Whenever you gain life, draw a card and put a
+1/+1 counter on Gestrag.
Whenever an opponents' spell targets Gestrag,
you may put Gestrag into your hand. If you do,
when you cast it from your hand for the second
time, Gestrag enters the battlefield with a lifelink
counter on it.
