The more I think about Dark Gardevoir for Masquerade the more I'm not sure it isn't a top tier again. Fezendipiti is actually insane the more I think about it. 120 HP so 5 energy attachments to swing for 150, 1 manual Luminous/Darkness attach for 180, Monkidori damage swap to take you to 80 HP, meaning two more attachments for 240, plus 30 for moving that damage to the opponent's active, Moonlit Hill heals another 30 so two more attachments for a total of 330. That's the extreme scenario, but it's 9 Psychics plus one Darkness, which shouldn't be too tough to get since you're binning every Psychic you find all game. You then have a coin flip to live any attack and take another 330 knockout because Monkidori can just keep moving damage around. You also have Flutter Mane to shut off Iron Thorns and reestablish another Fezendipiti. The only question mark I can see is bench space since the Kirlias and Gardy are relegated to support now, but I can see this deck being insufferable to play against, even if they don't get the best possible setup they can just flip heads enough to win.
