- 8 June 2018You don’t need to choose the name of a card anyone intends to cast this turn. You also don’t need to choose the name of a card that can have its cost reduced. For example, some Cheering Fanatics are enthusiastic about Shock or Mountain.
- 8 June 2018Effects that reduce the generic mana cost of a spell can’t reduce that spell’s colored mana requirements.
