Eruptive Titan

Eruptive Titan can't attack as long as it has fewer
than nine +1/+1 counter on it.
At the beginning of your upkeep, put three
+1/+1 counters on Eruptive Titan. Then, if it
has nine or more +1/+1 counters on it, it deals 3
damage to each other creature.
At the beginning of your end step, if Eruptive
Titan has nine or more +1/+1 counters on it,
remove all +1/+1 counters from it.
