Mega Gardevoir Glass Cannon; "Psychic Realities"

This deck, inspired by the Psychic Elegance deck from the 2023 World Championships, is designed to compliment Zacian V, Gardevoir, and Mega Gardevoir ex as well as possible. It does so by using Gardevoir ex's signature ability which allows quick energy attachment to your pokemon, and with the help of Mega Gardevoir ex, you can deal up to 800 damage in one blow before accounting for weaknesses, and a respectable 300-ish with Zacians Storm Slash or Gardevoir.

Kirlia and Radiant Greninja add powerful draw engines with Refinement and Concealed Cards, and supporters such as Iono and Professor's research make sure you are never short on the right cards. (Update Note: Gardevoir was re-added. Despite there only being 4 Kirlia and 6 Gardevoir cards, you can use Rare Candy to evolve Ralts into any of them and Gardevoir's ability was too strong to pass up on. Removed Drifblim and Drifloon because Gardevoir syncs with the other cards better.) 

(Update 2: Removed choice belt ×2 to better function with mega ex cards, and removed Zacian V ×1 because you can only use his Roar of The Sword ability once per turn. Added Rare Candy ×1 to make having Gardevoir, Gardevoir Ex, and Mega Gardevoir simultaneously active easier. Added Arven ×2 to make finding Rare Candy easier.) 

I would love to hear anything you all would change! Thanks so much.
