Mastery Spells
- 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.
- 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.
- 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.
