After using Clefairy's "Moon-Watching Party" Ability, if I switch or retreat for a benched Clefairy can I use its "Moon-Watching Party" Ability too?
Moon-Watching Party can be used by multiple different Clefairy if you get them into the Active Spot. However, if you bring up a Clefairy that has already used its Moon-Watching Party Ability this turn, it cannot use it a second time.
