Crypt Ghost

Whenever you tap a Swamp for mana, Crypt Ghost gains extort until end of turn. (Whenever you cast a spell, you may pay {w/b}. If you do, each opponent loses 1 life and you gain that much life.) (Multiple instances of extort on a permanent trigger separately.)
{t}, Pay 3 life: Add {b}{b}{b} or {w}{w}{w} to your
mana pool.
It's just the wind.
