x2Perfection
This Pokémon can use the attacks of any Pokémon-GX or Pokémon-EX on your Bench or in your discard pile. (You still need the necessary Energy to use each attack.)
[+] Miraculous Duo-GX: 200 damage. If this Pokémon has at least 1 extra Energy attached to it (in addition to this attack’s cost), heal all damage from all of your Pokémon. (You can’t use more than 1 GX attack in a game.)
Does Aerodactyl GX's "Primal Winds" Ability add 
to the cost of an attack used by Mewtwo & Mew GX's "Perfection" Ability if it tries to use an attack from a non-Basic Pokemon?
Yes, it does. Mewtwo & Mew GX is still a Basic Pokemon; it doesn't matter whether Perfection uses the attack from a non-Basic Pokemon or not.
