An AI deck builder that doesn’t invent cards

A generic chatbot hands you a list with two cards that don’t exist and one that’s banned. An AI grounded in the real catalog hands you a deck you can play.

The difference is where the AI looks

Every suggestion is checked against the game’s real catalog, set and number included: if it proposes it, it exists.

It works on your deck: it sees what you’ve built and suggests in context, not from scratch every time.

It validates the format: card legality and deck sizes checked automatically.

It answers in your language, with card names properly referenced.

How to get the most out of it

Answer quality tracks question quality. State the goal ("aggressive low-cost deck"), the context (format, budget, only cards I own), and ask for the why behind each change. And the trick almost nobody uses: ask it to critique your deck — "what’s the weakest point?" is usually the session’s best answer. The full guide is in how to build a deck with AI.

It works with Pokémon, Magic, and the rest of the catalog. If your collection is already inventoried, you can have it build only with cards you own — it completely changes the suggestions.

What the AI does not do

It doesn’t guarantee competitive decks: the metagame shifts weekly and winning tournaments is still on you. What it speeds up is the desk work: finding the card that fills a gap, comparing two options for the same role, reviewing the curve before you call it done. Distrust any tool promising otherwise.

Frequently asked questions

How many suggestions does the free plan include?

A daily quota to try it and build your first deck. Paid plans raise it for long building sessions. It resets every day.

Does the AI know which cards I own?

It knows which deck you’re editing and works in that context. To build only from your collection, say so in the request — it’s a constraint it understands.

How do I know suggested cards exist?

Each one is checked against the real catalog before showing, with set and number. That’s the structural difference from a generic chatbot.

Which formats does it validate?

The current formats of each game: Standard and Expanded in Pokémon; Standard, Pioneer, Modern, or Commander in Magic, among others.

Can it build the whole deck for me?

It can propose a full base, but the best results come from collaboration: you bring the idea, the AI fills gaps and flags problems.
