Updated June 9, 2026Koraidon ex and Darkrai Deck Guide in Pokémon TCG Pocket
A dual-type aggro deck that chips with Nightmare Aura, stalls with sleep, and closes with one explosive Legendary Drive turn
This deck pairs the Darkness Darkness disruption package of Darkrai and Darkrai ex with Koraidon ex, a Fighting Fighting attacker that can hit for 110 out of nowhere thanks to its Legendary Drive ability. The plan is simple: rack up passive damage and sleep turns early, then drop Koraidon ex from hand, pull every Energy in play onto it, and start taking knockouts. Every Pokémon in the list is a Basic, so the deck sets up fast.
The decklist
How it works
Koraidon ex is the finisher. World Wrecker costs Fighting
Fighting Fighting and hits for 110,
discarding the top card of your deck each time. The real engine is Legendary
Drive: once during your turn, when you put Koraidon ex from your hand onto
your Bench, you may switch it with your Active Pokémon and move all of your
Energy in play onto it. That means you can bank Energy on other Pokémon for
several turns, then promote a fresh 150 HP attacker that is immediately ready
to swing.
Darkrai ex is your early game. Its Nightmare Aura ability deals 20 damage to
the opposing Active Pokémon every time you attach a
Darkness Energy from your Energy Zone to it, so it
pressures the board before it ever attacks. Dark Prism costs
DarknessDarkness
Colorless for a clean 80, and with 140 HP it usually
survives long enough to attack twice. Aura chip plus Dark Prism puts most non
ex attackers in knockout range fast.
The regular Darkrai is the glue. Dark Void costs Darkness
Darkness Colorless for 60 and puts the
opposing Active Pokémon to Sleep, which can shut down a whole turn if the wake
up flip fails. Because it is not an ex, your opponent only earns 1 point for
knocking it out, so it is the perfect Pokémon to leave in front while you
stockpile Energy. Its 110 HP is respectable for a single point attacker.
The trainer suite keeps everything flowing. Poké Ball pulls a random Basic from your deck, and since every Pokémon here is a Basic it always finds a live body. Pokémon Communication swaps a Pokémon in your hand for a random one from your deck, turning a spare Darkrai into a missing Koraidon ex. Professor's Research draws 2 cards, X Speed cuts your Active Pokémon's Retreat Cost by 1 for the turn, and Potion heals 20.
Matchups
| Matchup | Favorability | How to play it |
|---|---|---|
| Giratina ex and Darkrai ex | Favored | Their Darkrai ex chips you, but yours chips back while Dark Void sleep turns steal their tempo. Two World Wreckers remove a 150 HP Giratina ex, and your Legendary Drive turn usually arrives first. |
| Bellibolt ex and Magnezone | Favored | This slower deck needs time to assemble its board, and your all Basic lineup attacks first. Lead Darkrai ex, stack Nightmare Aura damage every turn, and save Koraidon ex to clean up survivors. |
| Mega Lucario ex and Darkrai | Even | Both sides race with chip damage, but remember that knocking out their Mega ex awards 3 points and wins on the spot. Use Dark Void to slow their setup, keep Potion for your Active attacker, and aim Koraidon ex at the Mega once it commits. |
| Mega Sceptile ex and Teal Mask Ogerpon ex | Unfavored | Both Darkrai and Darkrai ex are weak to Grass  Grass, so their attackers hit your dark side for an extra 20. Pivot the game plan onto Koraidon ex, which takes neutral damage, and spend your sleep turns buying time to charge it. |
| Flutter Mane ex and Mega Gardevoir ex | Heavily unfavored | Koraidon ex is weak to Psychic  Psychic, so every hit lands 20 harder and your finisher folds early. Lean on the Darkrai pair, fish for consecutive sleep flips, and only commit Koraidon ex when it can take a knockout immediately. |
Tech options and swaps
The flexible slots are the Tools and Tool hate. Ancient Booster Energy Capsule is a Tool that supports Ancient paradox Pokémon like Koraidon ex; it is a Tool only, never an attached Energy, so it does not pay attack costs. Guzma discards every Tool attached to your opponent's Pokémon, and Field Blower offers similar cleanup of opposing Tools and Stadiums as an Item, so it does not compete with your Supporter for the turn. Against fields light on Tools these are the first cuts, but against Tool heavy lists keep all three.
How to pilot it
- Going first means no Energy attachment on turn 1, so use that turn to place Pokémon and dig with Poké Ball. The ideal opener is Darkrai or Darkrai ex up front with a second attacker on the Bench.
- Your Energy Zone generates one Energy per turn and can produce either Darkness or Fighting in this deck. Send every Darkness attachment to Darkrai ex to trigger Nightmare Aura for 20, and park Fighting attachments anywhere safe, because Legendary Drive collects them later.
- Use Dark Void early. Sixty damage plus Sleep forces a wake up flip, and a failed flip is a free turn of chip damage and Energy banking for you.
- Hold Koraidon ex in hand. Legendary Drive only triggers when it comes down from your hand onto the Bench, so it does nothing for a Koraidon ex already in play. Wait until three Fighting Energy are in play, then deploy it, switch it in, and swing for 110.
- Sequence Items before attacking. X Speed gets a damaged Darkrai out of the Active spot cheaply, and Potion is best spent keeping Darkrai ex alive for one more Aura trigger.
- Manage points. Feed the opponent the 1 point Darkrai while protecting your ex attackers, because each surrenders 2 points and the game ends at 3.
The most common misplays are benching Koraidon ex early just to feel safe, which wastes Legendary Drive, and stacking Darkness Energy that cannot pay World Wrecker's triple Fighting cost. Also remember the Bench holds at most 3 Pokémon, so leave a landing spot for your second Koraidon ex.
Deck strengths
- Every Pokémon is a Basic, so setup is fast and Poké Ball always hits
- Nightmare Aura generates damage every turn without attacking
- Dark Void sleep turns disrupt slower decks badly
- Legendary Drive lets Koraidon ex skip the usual charging turns in the Active spot
- A 1 point wall in Darkrai protects your 2 point ex attackers
Deck weaknesses
- World Wrecker needs three Fighting Energy exactly, so a Darkness heavy run of attachments stalls it
- Both Darkrai cards share a Grass Grass weakness while Koraidon ex carries a Psychic Psychic one
- World Wrecker discards the top card of your deck, which can mill a card you needed
- Professor's Research is the only raw draw, so some hands run out of gas
Is it worth building?
Yes, if you enjoy aggressive decks with a timing puzzle at their core. The Darkrai engine is cheap for anyone who has played Darkness decks before, and Koraidon ex is the only new investment. It will not outmuscle the format's top Mega ex strategies, and the Psychic Psychic matchup is genuinely rough, but patient Energy banking and well timed Legendary Drive turns deliver wins that feel earned.
