If I have 2 {P} Energy and an Aurora Energy or a Rainbow Energy attached to a Galarian Articuno and I use its "Psylaser" attack, do I have to discard the Aurora or Rainbow Energy since I'm not using them as {P} Energy?
Yes. Aurora and Rainbow Energy provide all types of Energy all the time when they are attached to a Pokemon, even if you don't want them to.
