Brahn, Crooked Confidant

Sacrifice another creature: Draw a card.
Whenever another creature you control dies, you lose life equal to its converted mana cost.
"Ay, kid you got the money? You don't? Okay... so I guess you don't know how it works 'round here. But learnin's for losers so you ain't gonna have the chance to know!"
