Lotta SV proxies here lol, Garde V is Gardevoir EX, Klefkis are the new Ability Lock Key, Belts are Defiant Bands, Tropical Beach is Beach Court, Irida is Arven, and Pokemon Center Lady is Miriam. Basic idea is sit on Keys while you set up your bench, mostly relying on Refinement Kirlia, and Judges to disrupt the opponent. Mirage Step Kirlia offers you a faster set-up if Klefki doesn't do much. Shining Arcana Garde is probably your main attacker here, can easily 2 shot provided you have enough mana in grave, and acts as a 1 prizer until you're ready to go in with the EX or a big Zacian V.
