The Bloodmad Hermit

Whenever a source you control would cause
you to lose life, create that many Blood tokens.
Sacrifice X Blood tokens: create an X/X Blood Golem artifact creature token with Menace
and {1}, sacrifice this artifact, discard a card: draw a card.
Sacrifice X Blood tokens, {t}: deal X damage to any target.

I told myself to cut out the bloodletting. Unfortunately, that guy never listens.
