Ichor, the Blood God

Indestructible
Ichor, the Blood God isn't a creature unless it
has Ten or more +1/+1 counters on it.
Whenever you would gain life, you may instead
put that many +1/+1 counters on Ichor, the
Blood God.
Remove X +1/+1 counters from Ichor: Another
target creature you control gains +X/+X and
Lifelink until end of turn. Sacrifice that creature
at the beginning of the next end step.
