如果你以「支付其法术力费用以外的其他费用」的方式来施放咒语，则你不能选择支付其任何替代性费用来施放之。不过，你可以支付额外费用。如果该牌含有任何强制性的额外费用，则必须支付之，才能施放此牌。
If you cast a spell for another cost "rather than paying its mana cost," you can't choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, those must be paid to cast the card.
