If Temple of Sinnoh is in play, can I use Archeops' "Primal Turbo" Ability to attach a Rapid Strike Energy from my deck to a non-Rapid Strike Pokemon?
Yes, you can use Primal Turbo to attach Rapid Strike Energy to a non-Rapid Strike Pokemon. Normally Rapid Strike Energy would be discarded immediately, but Temple of Sinnoh removes all effects of Special Energy attached to Pokemon, so Rapid Strike Energy would not be discarded. But if Temple of Sinnoh's effect goes away, then Rapid Strike Energy would be discarded.

If Temple of Sinnoh is in play and a player has a Basic Rapid Strike Sobble with a Rapid Strike Energy attached, and the player evolves to a Drizzile which is not a Rapid Strike Pokemon, does the Rapid Strike Energy get discarded or not?
Since the Rapid Strike Energy is already attached, it stays attached to Drizzile while Temple of Sinnoh is in play; however, it would be discarded from the Drizzile when Temple of Sinnoh leaves play.

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.

If Temple of Sinnoh is in play, does Double Turbo Energy provide one energy or two.
It would only provide one {C} Energy and would not reduce the Attack damage.
