白熱の熟達 {3}{R}{R}

ソーサリー

あなたはこの呪文のマナ・コストを支払うのではなく、{2}{R}{R}を支払ってもよい。

その{2}{R}{R}のコストが支払われていたなら、対戦相手１人は、自分が望む枚数のカードを捨て、その後その枚数に等しい枚数のカードを引く。

あなたのライブラリーからカード最大３枚を探し、あなたの手札に加え、ライブラリーを切り直す。その後、カード３枚を無作為に選んで捨てる。

If the {2}{R}{R} cost was paid, the opponent chooses how many and which cards to discard as Fervent Mastery resolves. They may choose to discard no cards. (2021-04-16)
The mana value of a spell on the stack is determined by its mana cost, not any alternative costs you used to pay for it. (2021-04-16)
If you choose to pay one alternative cost, you can’t pay any other alternative costs. For example, if an effect lets you cast a “Mastery” spell “without paying its mana cost,” you can’t also choose to pay its given alternative cost. (2021-04-16)

If an effect increases or decreases the cost of spells you cast, that cost increase or decrease is applied to the alternative cost you chose to pay. In that case, the cost was still paid for the purposes of the effect, even if you paid more or less for it when it was cast. (2021-04-16)
If you copy a “Mastery” spell and the alternative cost was paid, the copy will resolve as though the cost was paid. (2021-04-16)
In a multiplayer game, you choose which opponent takes the prescribed action as the spell resolves. (2021-04-16)
