How to build a Pokémon TCG deck: a step-by-step UK guide

To build a Pokémon TCG deck, pick one main attacker, give it a full evolution line, fill around half the deck with Trainer cards that draw and search, and add only as much Energy as your attacks need — 60 cards exactly. The fastest way to learn what works is to start from a list that is winning tournaments now and change it, rather than starting from a blank page.

Deck counts are from eight lists that placed at Regional Championships in Frankfurt, Recife, Louisville and Nice in September and October 2026. Prices are Iconic's own, checked 26 October 2026.

Step 1: know the deck rules

The rules fit on a sticky note. Exactly 60 cards. No more than four copies of a card with the same name, except basic Energy. At least one Basic Pokémon, because you need one to start the game. One ACE SPEC card at most. For the Standard format — the one League Challenges and Regionals use — every card needs regulation mark H, I or J, the small letter in the bottom-left corner. An older card is still fine if a reprint of it carries a legal mark.

Step 2: choose what wins you the game

Every good deck has a plan for taking six Prize cards. Usually that is one main attacker, sometimes with a partner. Dragapult ex, the most-played deck in the format, wins with Phantom Dive: 200 damage to the Active Pokémon plus 6 damage counters spread over the opponent's Bench, so it sets up two or three Knock Outs at once. Alakazam takes a different route, with Powerful Hand doing 2 damage counters for every card in your hand.

If you are new, choose an attacker whose plan you can say in one sentence. Our best Pokémon decks right now page explains the ten strongest in plain English.

Step 3: build the Pokémon line

Evolution decks need enough copies of each stage to find them on time. The Louisville-winning Dragapult list runs 4 Dreepy, 4 Drakloak and 3 Dragapult ex — a 4-4-3 line — plus a few support Pokémon such as Munkidori and Dudunsparce. Stage 2 decks like Alakazam also play Rare Candy, which lets a Basic Pokémon evolve straight into its Stage 2.

Across the eight lists we checked, the totals were:

Deck	Pokémon	Trainers	Energy
Dragapult ex (1st, Louisville)	19	32	9
Basic Box (1st, Nice)	21	24	15
Alakazam & Dusknoir (1st, Frankfurt)	23	32	5
Hydrapple ex (3rd, Nice)	19	28	13
Festival Lead (3rd, Frankfurt)	19	36	5
Mega Sharpedo ex (3rd, Louisville)	20	31	9
N's Zoroark ex (4th, Recife)	17	36	7
Slowking (6th, Frankfurt)	22	28	10

Step 4: fill half the deck with Trainers

Trainers are what make a deck consistent. Most lists use the same jobs, filled by the same staples:

• Draw: a Supporter you can play almost every turn — four Lillie's Determination appear in most of the lists above.
• Search: Ultra Ball, Buddy-Buddy Poffin and Poké Pad find the Pokémon you need.
• Gust: Boss's Orders pulls the Pokémon you want to Knock Out into the Active Spot.
• Recovery: Night Stretcher gets Pokémon or Energy back from the discard pile.

These are also the cheapest cards in the deck. On 26 October 2026 our prices were Ultra Ball £1.00, Rare Candy £1.00, Buddy-Buddy Poffin £1.00, Poké Pad £1.20, Night Stretcher £1.20 and Boss's Orders £1.60.

Step 5: count your Energy last

Add Energy only after the rest is settled, and count from your attack costs. Decks with one- or two-Energy attacks and no way to accelerate run as few as 5; decks that attach extra Energy every turn, like Hydrapple ex with Teal Mask Ogerpon ex, run 13 to 15. If you keep drawing Energy you cannot use, cut one or two for another search card.

Step 6: test it, then change one thing at a time

Play ten games before you judge a list, ideally at a local Pokémon League where you can see what others play. Change one or two cards at a time so you know what made the difference. If your deck keeps stalling on the first two turns, it needs more search; if it runs out of attackers late, it needs more Pokémon or more recovery.

Step 7: buy the cards

When the list is done, paste it into our deck builder. It accepts the text export from Pokémon TCG Live or a Limitless link, checks every card against our shelves, picks the cheapest printing of each one, and adds everything we have to your basket in one click.
