Protect those Ralts! You’ll need them if you want to activate the deck’s optimal strategy. Setting up your board state with as many Ralts during your first turn is ideal but don’t forget to get your Mew from Celebrations in the active spot to have the ability ‘Mysterious tail’ to help find those Battle Vips, Nest Balls, Fog Crystals, Ultra Balls, etc. This deck usually includes an Artazon Stadium card to look for those basic Pokémon in the first turn.
Once you have those Ralts in play you’ll be able to evolve them to either Kirlia or Gardevoir’s if you have a Rare Candy in hand. Kirlia’s ‘Refinement’ ability provides draw power and consistency when finding the cards you need throughout the battle along with Gardevoir’s ‘Shining Arcana’. The offensive tactic of this deck is turned on with Gardevoir ex’s ‘Psychic Embrace’ ability and the reversal energy to get those knockouts on the counter. Powering up your heavy hitters like Gardevoirs, Scream Tail, Zacian V with Gardevoir’s ‘Psychic embrace’ allows your Cresslia to attack and potentially knock out any low Hp pokemon on the bench with ‘Moonglow Reverse’ attack.
