Undaunted (This spell costs less to cast for each opponent.)
Destroy two target creatures.
You canâ€™t cast Curtainsâ€™ Call without two creatures to target. If one becomes an illegal target after youâ€™ve cast Curtainsâ€™ Call, the other will still be destroyed.
Effects that reduce what you pay to cast a spell donâ€™t affect its converted mana cost. Sublime Exhalationâ€™s converted mana cost is 7, regardless of how many opponents you have or how much mana you spent to cast it.
Causing an opponent to lose the game after youâ€™ve announced that youâ€™re casting a spell with undaunted and determined its total cost wonâ€™t cause you to have to pay more mana.
