Curse of Karness Muur

When this card is played, target and enchant an opponent.
Whenever the enchanted player plays a Being or Creature card, they place an Infected counter on
that card. At the start of each player's turn, they
place a -1/-1 counter on each card with an
Infected counter and when a card reaches 0 for
their defense value, destroy it and they create a
1/1 Rakghoul Token with Overwhelm and
Rakghoul Plague on your field.
