Sing Together
The Sing Together keyword represents a static ability that allows a player to pay an alternate cost to sing a song with one or more of their or their teammates’ characters. Sing Together N means “You and your teammates may pay, ‘ ! a number of your characters with total ink cost N or greater’ to play this card instead of its ink cost, where N is the ink cost of the song.
When playing a song using Sing Together, add the ink costs of one or more of your ready characters together. If the total meets or exceeds the cost listed for Sing Together, the character or characters can sing the song.
Characters that have the triggered ability condition “Whenever this character sings a song” and are one of the characters singing the song with Sing Together, the condition is met, and the triggered ability is added to the bag to resolve.
