Field notes
The deck builder is described as accepting .ydk files and ydke:// links from YGOPRODeck, Duelingbook, or EDOPro, then checking lists against format rules. The page also says tournament top decks from YGOPRODeck can be opened from the builder. Ranked matches include siding between games and a match clock; the described board uses WebGL on desktop and phones.
