Rosco, Two Ton

Reach, Trample, Defender
Whenever Rosco, Two Ton takes combat damage
or a bear you control dies from combat damage,
spell, or effect an opponent controls Rosco loses
defender and gains a +1/+1 counter.
Rosco is probably the most calm and gentle
bear you will ever meet. Thankfully he prefers
to eat only fish. But never hurt him or one of
his kind. You don't want to see him angry..."
