Build Commander decks. Then prove they work.
Import a list from anywhere, price it against your collection, check every legality rule, and playtest it against a rules engine that enforces the stack, priority, layers, and combat — not an honor system.

Everything a deck needs before it hits the table
Bring a list from wherever it lives, price it against what you own, and know it's legal before you shuffle up.
Import & export
Paste a decklist or upload an MTGO .dek — mtgmatic resolves every name against Scryfall and flags anything it couldn't match. Export back out the same way.
Prices & collection
Every deck totals its live market value, and checked against your tracked collection it shows exactly what you still need to buy.
Legality
Singleton, color identity, the banned list, a valid commander — checked automatically, with the specific card and rule cited for every issue.
Stats
Mana curve, color pips, and type breakdown update as you build, so you see the shape of the deck, not just the count.
A rules engine, not an honor system
Most deck builders stop at the list. mtgmatic goes further: a real Magic rules engine that enforces the stack, priority, layers, and combat, so a game against the AI plays out the way the rules actually say it should.
