Rand, The Dragon Reborn

Ward: Sacrifice a nontoken permanent

When you cast a noncreature spell, lose 1 life and add {b}.
If this is the second time the ability has triggered, draw a card. If this is the third time, create two white and red 1/1 human warrier tokens with prowess and haste. If this is the fourth time, sacrifice a creature.

{t}, {x}{p/b}{b}{b}: Exile target instant or sorcery from an opponent's graveyard with mana value X. You may cast it without paying it's mana cost.
