Demon Of Blessings

Whenever a creature you control with one or
more counters on it dies, you may put a +1/+1
counter and those counters except for -1/-1
counters on Demon Of Blessings. When you do,
exile that creature.
{3}: Put a -1/-1 counter and your choice of a
flying, lifelink, trample or vigilance counter on
another target creature you control.
The child knows the price. It's worth it.
