부여마법 — 마법진
생물에게 부여부여된 생물은 당신이 조종하는 늪 하나당 -1/-1을 받는다.
The ability cares about lands with the land type Swamp, not necessarily lands named Swamp.
This ability counts the number of Swamps controlled by Quag Sickness’s controller, not the enchanted creature’s controller (in case they’re different players).
This bonus is not fixed; it changes as the number of Swamps you control changes.
