That is a black triggered ability, not red. And at that cost, with such a small payout, I would suggest it destroy the creature on blocking rather than combat damage.
When I saw the name, my initial though was that he was somehow related to Griselbrand...

Curiously, you can get the token even if the other creature was already destroyed with the combat damage.

2 toughness also doesn't bode well for getting too much value out of this.

@Link: I didn't name him, he's from the book Eragon. That's what this block is based on.

Ah, yes. I read that book ages ago and I've purged most of it from my memory.
