Fireclaw

Trample
Fire counters have no effect on creatures you
control. Fire counters on creatures you don't
control deal X plus 3, where X is equal to half
the creature's toughness.
When Fireclaw takes damage, put a fire counter
on Fireclaw, then until the end of the turn,
Fireclaw has +1/+0 for every fire counter on it
Removed 3 fire counters: Fireclaw's toughness is
equal to Fireclaw's Power and it gains hexproof
until your next turn
