Mega Gardevoir ex is played with Genetic Apex's Mewtwo ex in this deck as a way to KO non-Mega ex Pokemon cleanly. Mega Gardevoir ex can consistently set up Mewtwo ex for multiple attacks, and retreat to safety thanks to Peculiar Plaza's Retreat Cost reduction.
Meloetta is the deck's ideal starter, as it can easily find you your key setup pieces with its Strange Singing Ability.

Fantastical Parade brings us Mega Gardevoir ex, and along with it are high-synergy cards to slot into your Mega Gardevoir ex decks.
Diantha heals 90 damage from your Psychic Pokemon, but comes at the cost of discarding 2 Energy. This is a small inconvenience for Mega Gardevoir ex, who easily floods your board with Energy.
Peculiar Plaza gives your Psychic Pokemon flexibility by allowing you to retreat whenever you have to.'
Use these cards together, and score victories with Mega Gardevoir ex!

Slotting in Indeedee can help you deal 70 damage to your opponent's Bench. While this may not be that useful against an Active Pom-Pom Oricorio, this could open up Cyrus plays later in the game.



Mega Gardevoir ex can be played with Psychic-types that offer utility, besides just offense.
Indeedee ex helps keep your Pokemon healthy, and can be useful offensively against opposing Mega Gardevoir ex thanks to its Psychic being able to deal meaningful damage to it if they attach Energy carelessly.
Meloetta can thin out your deck and find necessary Pokemon cards.
Mimikyu ex and its Disguise Ability allows it to always stay on the field for more than one turn, buying you valuable setup time.


Hydreigon is difficult for Mega Gardevoir ex to go up against. Even after a Roar in Unison, Hydreigon still sits safely at 120 HP, comfortably out of Mega Gardevoir's KO range.
Missing KOs on this Pokemon can prove costly in this matchup, as it lets the Hydreigon player set up another attacker to finish Mega Gardevoir ex.

a good counter against Mega Gardevoir could be Jolteon EX’s ability, since the damage for it’s energy attachment stacks.
