Undaunted (This spell costs {1} less to cast for each opponent.)
Destroy all creatures.
Causing an opponent to lose the game after you’ve announced that you’re casting a spell with undaunted and determined its total cost won’t cause you to have to pay more mana.
Effects that reduce what you pay to cast a spell don’t affect its converted mana cost. Sublime Exhalation’s converted mana cost is 7, regardless of how many opponents you have or how much mana you spent to cast it.
