Ye'Ran, the Sufferer

Whenever you spend mana, you lose 1 life for each black mana spent.
{b}, Sacrifice a permanent: Gain 2 life.
At the beginning of your end step, reveal cards from the top of your library until you reveal a black card. Exile that card, then shuffle all other revealed cards into your library. Cast that card without paying it's mana cost. You lose life equal to it's converted mana cost.
