Constellation Appeal (星座アピール ; seiza apīru) is a keyword introduced in CB14. Each effect with this keyword can be different, but all of them has either one of the following common parts:
- "by sending Soul Core from this Spirit to the Trash, [additional effects]"
- "you can send Soul Core from this Spirit to the Trash. When you've done so, [additional effects]"
While also "Appeal"-named, Constellation Appeal isn't treated as Appeal, meaning any effects that target Appeal don't target Constellation Appeal.
As the name suggests, the keyword represents the 12 western zodiacs, hence it's exclusive to "Coord"-named Spirits with the coords of the same theme.
