Balda H'ur, the Jungle Rot

{b}{g},{t}: Target instant or sorcery card in your
graveyard gains flashback until end of turn.
The flashback cost is equal to its mana cost.
Whenever a player casts an instant or sorcery
spell from a graveyard, you may destroy target
land you control, if you do you may search
your library for two swamp cards and put
them into your hand.
