单卡释疑

  要计算咒语的总费用，先从要支付的法术力费用或替代性费用开始（例如鼓舞的替代性费用），加上费用增加的数量，然后再减去费用减少的数量。无论施放咒语的总费用为何，该咒语的法术力值都不会改变。

  To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as the alternative cost of Invigorate), add any cost increases, then apply any cost reductions. The mana value of the spell remains unchanged, no matter what the total cost to cast it was.

  如果有效应注明对手不能获得生命，则你不能让该牌手获得生命来支付鼓舞的替代性费用。如果有效应改为替代获得生命之动作（例如硫磺旋风），则就算该费用的动作被替代为「无」，你也可以选择支付该费用。

  If an effect says that an opponent can't gain life, you can't have that player gain life to pay Invigorate's alternative cost. If an effect instead replaces life gain, such as that of Sulfuric Vortex, you may choose to pay the cost even though the cost's action is replaced with nothing.
