Deck legality checker

Paste your decklist straight from Arena, Moxfield, MTGO or Archidekt and pick the format. We check banned and restricted cards, copy limits, deck and sideboard size and, in Commander, color identity.

Format
Bracket, combos and the deck x-ray are Commander-only; other formats get a legality check.

Which format is for you?

Which cards each format allows, what a deck costs to build and where it is played, in the formats guide.
