Malachor V

While Malachor V is on your field, cards with
White as a color that attack you have their attack
values reduced by 3 and their ability costs
increased by {2}.
If the opponent has been enchanted with Curse
of Nihilus or Curse of Traya while Malachor V is
on your field, you can summon a Forceful Being
card from their Netherworld but change their
color and ability costs to Black and their
archetype to Sith.
