伝説のアーティファクト
ニクスの睡蓮はタップ状態で戦場に出る。

:色1色を選ぶ。あなたのその色への信心に等しい点数の、その色のマナを加える。(あなたの色への信心とは、あなたがコントロールしているパーマネントのマナ・コストに含まれるその色のマナ・シンボルの総数である。)
If you put an Aura on an opponent’s permanent, you still control the Aura, and mana symbols in its mana cost count towards your devotion.
Mana symbols in the text boxes of permanents you control don’t count toward your devotion to any color.
If an activated ability or triggered ability has an effect that depends on your devotion to a color, you count the number of mana symbols of that color among the mana costs of permanents you control as the ability resolves. The permanent with that ability will be counted if it’s still on the battlefield at that time.
Hybrid mana symbols, monocolored hybrid mana symbols, and Phyrexian mana symbols do count toward your devotion to their color(s).
Nyx Lotus’s second ability is a mana ability. It doesn’t use the stack and can’t be responded to.
