Satan, Pain born

Instead of paying this creature's mana cost you
may pay 1 life instead for each land you would spend to cast this creature, If you do for every life spent to cast this creature this does 2 damage to target creature or player. Whenever you cast a spell you may instead pay X life where X is the spells converted mana cost. Whenever you lose 1
or more life your opponent must sacrifice a nonland permanent. They lose life equal to the cards converted mana cost.
