Sanguine - Whenever a creature dies, you may sacrifice a land, if you do, search your library for
a card and put it into your hand. You lose 2 life.
{b/g}{b/g}{b/g}, {t}: If black was paid to cast this, you
may search your library for a basic swamp and
put it onto the battlefield tapped, if green was
paid you may search for a basic forest instead.
Activate this only if a land left the battlefield
