Kaiju

Whenever a creature you control overrides, put
a +1/+1 counter on Kaiju.
{b}{w}, remove four +1/+1 counters from Kaiju:
destroy target non-land permanent, then gain life
equal to that permanents converted mana cost.
One of the most fearsome battlemechs that ever existed,
the Kaiju elected to replace its signature AC20 Deathgiver autocannons with a pair of PPCs for
longer engagements, one in each arm.
