집중마법
경쟁자 제거를 발동하기 위한 추가비용으로, 생물 X개를 희생한다.
생물 X개를 목표로 정한다. 그 생물들을 파괴한다.
If you somehow cast Eliminate the Competition without paying its mana cost, you'll still choose a value for X and sacrifice X creatures.
Once you announce that you're casting Eliminate the Competition, players can't try to remove creatures you'd like to sacrifice.
