Whenever a creature you control mutates for the
first time each turn, put a +1/+1 counter on that
creature and draw a card.
Ferocious—Whenever a creature under your
opponents control dies, you may pay {x} where X
is the mana value of that creature plus the
number of time that target creature you control
has mutated. If you do mutate your opponent's
creature under your creature. You may activate
this ability only once each turn.
