The app already writes your deck out as a forum code. Paste it below and it can go up for other people to scan straight into their own Deck Builder.
Needs version 11.1 or newer. On an older build, or if you’d rather not, the form below does the same job.
If you still have the app, the quickest way is the ⋮ menu on the deck — Ask for removal. This form is here for anyone who no longer has the app, or the deck, and wants theirs off the site.
