I jus received confirmation from the developer that Calculords multiplayer will be asynchronous. Perhaps this was a given, given the potential length of a single turn in the game, but it is still nice to see it corroborated by the developer himself
Waiting on confirmation on a query as to whether multiplayer will have any form of progression (either shared with single player, or a separate system), with card collection and deck building, or just one-off matches with preconstructed decks. Hopefully, the former, but with premade/even/balanced decks as an option for competitive play (with separate leaderboards, rankings, etc).
(With a progression system extensive and inspiring enough, we might finally have a TCG with online play and persistant progression to fill the void left behind by Recollection. Also, it would be the first TCG to offer async play (since Cabals never delivered on that promise), which is an enormous advantage for those of us who can't find the time for extensive online sessions.)
