- If Temple of Sinnoh is in play, does Meloetta's "Melodious Echo" attack still do 70 damage for each Fusion Strike Energy attached?
- Yes. Temple of Sinnoh removes all effects and provides 1 Colorless energy, but it does not change the card name to be something other than "Fusion Strike Energy". So Melodious Echo still does 70 damage for each attached Fusion Strike Energy you have in play.
