How to read these trends
Public Limitless tournaments, not ranked ladder results. Each point is a rolling window of up to 30 days and 30 eligible events. Historical rates are approximate because stored deck rates were rounded. History follows the builds currently accepted for this page, including archived builds; only records present in each snapshot count. Win rate is wins divided by wins, losses and ties, including mirror matches. Entries and game records are not unique players or deduplicated matches; overlapping windows must not be added together.

Which Trainer Cards Do Diancie Decks Use?Mega Diancie ex deck guide: build a board of Psychic Energy
Count Psychic Energy across the whole board
A Mega Diancie ex deck builds damage across your board. Mega Diancie ex B3b-032 is a 170-HP Basic. Brilliant Storm costs three Colorless Energy and deals 40 plus 20 for every Psychic Energy attached to all your Pokémon. Three Psychic Energy in play gives 100 damage; six gives 160, before modifiers. Its knockout gives the opponent three points, so the Diancie deck must weigh another attachment against exposing its attacker.
Give Carbink two Benched targets
The Carbink Diancie deck uses Carbink B3b-031. For one Psychic Energy, its attack gives one Psychic Energy from the Energy Zone to each of two chosen Benched Pokémon. It cannot put both on one target. If both added Psychic Energy remain attached to your Pokémon, a later Brilliant Storm gains 40 damage. Prepare two useful recipients before committing the attack. In thischase’s November 1 submission, two Mega Diancie ex share space with two Carbink, Flutter Mane and Comfey; that is one real Diancie deck example, not the statistical list above.
Evolve before relying on Gardevoir’s attack
The Gardevoir Diancie deck has a different setup cost. Mega Gardevoir ex B2-066 evolves from Kirlia; its two-Psychic attack deals 110, then distributes three Psychic Energy among your Psychic Pokémon. If that Energy remains in play, it adds 60 to the next Brilliant Storm. JuanTheMan’s November 2 submission has two Ralts, two Mega Gardevoir ex and two Rare Candy A3-144, without Kirlia. Rare Candy cannot work on your first turn or on a Basic played that turn. This Diancie deck therefore depends on both the evolution pieces and their timing.
Use Mewtwo’s Stadium condition deliberately
The Mewtwo Diancie deck includes Mega Mewtwo X ex C1-056, a Basic with both Psychic and Fighting types. Its attack costs two Psychic and one Colorless Energy: 100 damage, or 140 while a Stadium is in play. This offers a fixed Stadium-based threshold alongside Brilliant Storm’s board-wide scaling. Both attackers give up three points when knocked out. Choose between their attacks using the actual Stadium and Psychic Energy count; the Diancie deck does not get a safer point trade simply by changing attackers.
Keep retreating from consuming the damage bonus
In a Diancie deck, Peculiar Plaza B2-155 reduces every Psychic Pokémon’s Retreat Cost by two on both sides. Mega Diancie ex normally retreats for one, so this Stadium can preserve Energy that still counts toward Brilliant Storm. Flutter Mane B3b-035 needs to move from the Bench to the Active Spot during the same turn for its two-Energy attack to deal 90; otherwise the attack does nothing. Plan that movement before attacking. The opponent also receives the Stadium’s retreat reduction.
Healing can remove forty damage from the next attack
The Gardevoir Diancie deck example uses Diantha B2-149: heal 90 from one of your Psychic Pokémon with at least two Psychic Energy, then discard two Psychic Energy if any damage was healed. Without replenishment, Brilliant Storm loses 40 damage. Eviolite C1-123 instead reduces opposing attack damage by 20 on the attached Basic, which includes Mega Diancie ex. Comfey A3-080 removes and prevents Special Conditions only for your Pokémon with Psychic Energy attached. These protections have different costs; none proves that a Diancie deck survives every knockout.
Separate drawing cards from finding a Basic
A Diancie deck uses Professor's Research P-A-007 to draw two cards, while Copycat B1-225 shuffles your hand back and draws according to the opponent’s hand size. Neither selects a missing evolution. Poké Ball P-A-005 finds a random Basic, so additional Basic Pokémon can change what it finds. The Carbink submission has two Poké Ball; JuanTheMan’s Gardevoir submission has one. Those are observed choices in two Diancie deck examples, not evidence that one count is always better.
Choose the Energy engine before copying twenty cards
Start from the Diancie deck comparison and choose the engine your collection supports. The cited Carbink submission uses two Mega Diancie ex; JuanTheMan’s Gardevoir submission uses one. A Diancie deck with one copy therefore has a real example, but its evolution package is a separate commitment. Open the Carbink Diancie deck’s full twenty-card list or use the Deck Builder to inspect your cards. The on-site list is a statistical representative, not either player’s original submission. Compare tournament records with their samples; these Diancie deck results do not establish ladder strength.
