How it plays
Gardevoir ex's Psychic Embrace attaches a Basic Psychic Energy from your discard pile to one of your Psychic Pokémon as often as you like each turn, putting 2 damage counters on that Pokémon each time. That damage is the point: Drifloon's Balloon Blast does 30 for each damage counter on itself, so a Drifloon given four Energy by Gardevoir carries 8 counters and hits for 240.
Four Kirlia draw with Refinement (discard a card, draw 2), which also puts Energy in the discard pile for Gardevoir. The box adds Mew ex, Lumineon V and Radiant Greninja for drawing and searching. The skill is in counting: each attach is damage you are doing to yourself, and a miscount hands your opponent an easy Knock Out.
Is it Standard legal?
No. Gardevoir ex, Drifloon, Mew ex, Iono, Arven, Professor's Research, Jacq, Artazon, Nest Ball, Super Rod and Bravery Charm carry the G mark, and Kirlia, Ralts, Cresselia, Lumineon V and Radiant Greninja are older still. All of them have rotated. It is an Expanded deck now.
Every upgrade card below carries an H, I or J regulation mark, the marks legal in Standard since the April 10, 2026 rotation, checked against our Pokémon card catalog on October 10, 2026. Basic Energy is always legal. See which cards are legal in each format for how regulation marks and reprints decide it.
Upgrade path 1: Keep it for Expanded
The box list was built for Standard in 2024 and still works in Expanded, where every card is legal. The upgrades that matter are the ones that recur Energy and attackers. Night Stretcher gets back a Psychic Energy or a Knocked Out Drifloon, and Lana's Aid returns up to three Pokémon without a Rule Box or Basic Energy in any mix.
A second Boss's Orders is useful in any version: Drifloon's damage is high, and choosing its target is how it takes two Prize cards instead of one.
Night Stretcher
Ascended Heroes #196
Gets back an Energy or a Drifloon.
Lana's Aid
Twilight Masquerade #155
Up to three Drifloon, Kirlia or Basic Energy back to your hand.
Boss's Orders
Ascended Heroes #183
A third copy for picking targets.
What comes out: Jacq, one Bravery Charm and one Artazon.
Upgrade path 2: Rebuild it around Mega Gardevoir for Standard
The current Gardevoir is Mega Gardevoir ex, a different card with a different plan. Overflowing Wishes searches your deck for a Basic Psychic Energy for each of your Benched Pokémon and attaches one to each, and Mega Symphonia does 50 damage for each Psychic Energy attached to all of your Pokémon. Fill the Bench, attach, and the damage scales with the whole board rather than one attacker.
The current Kirlia has Call Sign, which searches for up to 3 Pokémon, so it sets up the Bench Overflowing Wishes wants. Mega Signal finds Mega Gardevoir ex directly, and Lillie's Determination replaces Iono and Professor's Research.
Mega Gardevoir ex
Ascended Heroes #89
Mega Symphonia: 50 for every Psychic Energy on your Pokémon.
Kirlia
Ascended Heroes #88
Call Sign searches for up to 3 Pokémon.
Mega Signal
Ascended Heroes #193
Searches for a Mega Evolution Pokémon ex.
Lillie's Determination
Ascended Heroes #192
Draw 6, or 8 before you take a Prize.
Buddy-Buddy Poffin
Ascended Heroes #184
Fills the Bench with Ralts.
What comes out: Everything rotated: Gardevoir ex, the old Kirlia, Drifloon, Mew ex, Lumineon V, Radiant Greninja and the G-mark Trainers.
