Paste a deck link from MTGGoldfish, MTGTop8, Moxfield, Archidekt or Scryfall. We’ll fill in the main deck and sideboard.
Open a deck on any of those sites, then copy its address here.
Have a text export? Paste it below.
Shortcut: put decklist.app/ in front of a deck’s address in your browser, and it opens here already imported.
(Pro tip: You can simply paste in MTG Arena, Moxfield, MTGGoldfish, MTGO, MWS, MTG Salvation, Deckbox "Print", or TappedOut "Text" decks, set codes and all, without separating out the sideboard!)
