Electro, Living Lightning

Electro, Living Lightning enters the battlefield
with X +1/+1 counters on it.
If damage would be dealt to Electro, Living
Lightning while it has a +1/+1 counter on it,
prevent that damage and remove that many
+1/+1 counters from it. When one or more
counters are removed from Electro, Living
Lightning this way, it deals that much damage
to any target.
