Raven-3L

Whenever Raven-3L becomes untapped, put a
+1/+1 counter on it.
Override—(When Raven-3L attacks, you may put
an overheat counter on it. Remove this counter at
the beginning of your next upkeep. An overheated
creature takes double damage from all sources.)
When Raven-3L attacks, if there is an overheat
counter on it, put a +1/+1 counter on it.
