The Ruinous Powers 毁灭大能
{2}{B}{R}
At the beginning of your upkeep, choose an opponent at random. Exile the top card of that player's library. Until end of turn, you may play that card and you may spend mana as though it were mana of any color to cast it. When you cast a spell this way, its owner loses life equal to its mana value.

在你的维持开始时，随机选择一位对手。放逐该牌手的牌库顶牌。直到回合结束，你可以使用该牌，且你可以将法术力视同任意颜色的法术力来施放该牌。当你以此法施放咒语时，其拥有者失去等同于其法术力值的生命。

利用咒语在堆叠上的法术力值（若咒语已被移出堆叠，则利用它最后在堆叠上时的此数值），来决定会失去多少生命。如果该咒语的费用中包含{X}，则在确定该咒语的法术力值时，会将为X选择的数值计算在内。
Use the mana value of the spell as it exists on the stack (or last existed on the stack, if it's been removed) to determine how much life is lost. If there is an {X} in that spell's cost, include the value chosen for X to determine its mana value.
