The product
Everything a Magic player needs, in one place
Counterdeck unifies tools that today live across 12 different sites. Built by a player, for players — in your language from day one.
Deck Builder
Build decks for Commander, Standard, Modern, Pioneer, Legacy and Pauper. Filter by color, cost, format and legendary. Export to Arena or MTGO in one click.
Online Simulator
Multiplayer table in your browser, Cockatrice-style. Free drag & drop, phases, scry, counters, life — everything you need to play.
AI Card Search
Ask in plain English: «red cards that gain life» or «green ramp at 2 mana». The AI translates to Scryfall and returns the results.
Marketplace P2P
Buy and sell cards directly between players. No 5–10 % commissions like Cardmarket — you only pay shipping.
Community & Forum
Discuss decks, formats and new sets. In your language, no tracking, moderated by people who actually play.
Collection
Track which cards you own per set and language. Know what you're missing to finish any deck before you buy.
