Your key stays in your browser. It is kept in this tab only (or on this device if you tick Remember) and sent only to the AI company you picked, straight from your browser. It never reaches pokemonpack.com, and we never see or store it. Your builds are billed to your own AI account; the shop pays nothing. A remembered key can be read by anyone using this browser: press Forget key when you're done on a shared computer.
An API key is like a password that lets an app use your own account with an AI company. You paste it here, and the deck builder uses your AI account to do its thinking. The AI company bills you for what you use, usually a few cents per deck.
Why we ask for one. The deck builder is free: we don't charge for it and we don't run the AI ourselves. Your key goes straight from your browser to the AI company you picked. We never see it, store it or take a cut.
A subscription is not an API key. ChatGPT Plus, Claude Pro, Gemini in the Google One plans and other app subscriptions don't include an API key or API credit. The API is a separate, pay-as-you-go account on the developer sites below (you can sign in with the same login).
sk-ant-).sk-; it's shown only once).Free tier: Google's Gemini API has a free tier: many models, including the Flash models, cost nothing within daily limits, with no card needed. On the free tier Google may use what you send to improve its products; on the paid tier it doesn't. The newest Pro models need billing turned on.
sk-or-).A build reads about 25,000 to 60,000 tokens and writes 4,000 to 9,000 (a token is about three-quarters of a word). With list prices on 8 Oct 2026:

Tell it your format, play style, budget and the cards you own. It looks up every card in the card database while it works, builds a legal Pokémon TCG Live (PTCGL) text list, then explains the game plan, the key combos, how to mulligan, tech options, budget swaps and the non-obvious synergies most players miss. Before you see the list, this page checks the card counts and legality again and flags any problem.
It works with Claude (Anthropic), GPT (OpenAI), Gemini (Google), or hundreds of other models through OpenRouter. You bring the key; open What's an API key? above for a two-minute how-to.
One click fills in the form and a detailed request that gets the most out of Spark. You can edit all of it before you press Build.
Deck names are suggestions from 2026-10-08; the meta moves fast, so check Limitless TCG: decks for this week's top decks.
Cards I own (optional: attach your TCGplayer, Collectr or other export, or just paste a few cards below, one per line)
Your collection stays in your browser. The file is read on your device and is never uploaded to pokemonpack.com or saved anywhere. When you press Build, only the card names and counts go to the AI you picked, and card names to the public card database. Reads Pokémon TCG Live deck text, Collectr, Dragon Shield and TCGplayer app exports (CSV or Excel .xlsx), or any list like “4 Nest Ball”.

Set up two Dreepy on turn one with Poffin and Nest Ball, then evolve straight to Dragapult ex with Rare Candy. Its attack hits the Active Pokémon and spreads damage counters on the Bench, so two attacks often take several Prizes at once.
Dusknoir's ability moves damage counters at the cost of itself: after a spread turn, it turns a near-KO into a knockout and can take the last two Prizes out of nowhere.
Keep any hand with a Dreepy or a search card. Going first, prioritise two Dreepy on the Bench over drawing cards.
Jamming Tower shuts off Tools; swap for a second Unfair Stamp against slower decks. Budget: Dusknoir line out, 2 more Counter Catcher in.

Finds flyer deals, sales, restocks, MSRP finds and new releases for Pokémon near you or online. The AI you picked searches the web with its own search tool, and every find comes with its sources and the date we found it.
Searches run on your own key. Each hunt uses your AI account's web search and may cost you a few cents, billed to your own AI account. The shop pays nothing and never sees your key.
Leave it empty to look at online shops only. Your area is kept on this device and sent only to the AI you picked, with the search.
AI finds can be wrong or out of date: the AI reads public web pages and we don't check its answers. Call the store before you go.
Where the winning Pokémon lists live. We link to these sites rather than copying them. Links checked 2026-10-08.
Most competitive decks land near 12 to 20 Pokémon, 30 to 40 Trainers and 6 to 14 Energy. Decks that search or recycle Energy run fewer; decks with heavy attack costs and no acceleration run more. Exactly 60 cards, no more than 4 of a card by name (Basic Energy excepted), one ACE SPEC and one Radiant Pokémon at most.
Your main attacker wants a thick line: 4-3-3 or 4-2-3 for a Stage 2, 3-3 or 4-3 for a Stage 1. Thin lines (1-1) are for support Pokémon you only need once a game. Count how many Basics you run: under about 8 Basics you will mulligan noticeably more often.
List every card that finds your setup (draw Supporters, Pokémon search Items, ability-based draw). A deck with 12 or more of these in 60 cards opens with at least one most of the time; fewer than 8 and you will see dead hands. Consistency wins more games than a clever tech card.
Every game is a race to take six Prizes. Two- and three-Prize Pokémon hit hard but give your opponent big chunks of the race. Pair a big attacker with a single-Prize attacker or a way to heal, so your opponent can't win in three knockouts.
Count how many attachments your main attack needs and by which turn. One manual attachment a turn is slow; acceleration (abilities or Trainers that attach extra Energy) changes the whole plan. Special Energy saves slots but is easier to remove.
Pokémon has no sideboard: tech cards live in the 60. Keep 3 to 6 flexible slots for the decks you expect (a counter Stadium, a switching card, a matchup answer) and cut them first when a list feels clunky.
Buy the Trainer staples first: they carry across many decks and sets. Build the cheapest version of one archetype and upgrade one line at a time. Single-Prize decks are often both cheap and strong. Check rotation dates (each April) before spending: cards with old regulation marks leave Standard.
