Haunted Grounds

Enchant land
As long as you control a Zombie, enchanted land
has "{3}, {t}: Exile target card from a graveyard."
As long as you control a Spirit, enchanted land
has "{4}, {t}: Target player discards a card."
As long as you control a Vampire, enchanted land
has "{5}, {t}: Return target card from your
graveyard to your hand."
