Looks like a bunch of new stuff has been tossed in to SolForge today.
Tournaments will allow players to compete with each other at their own convenience ("no waiting on other players to finish"), as well as guarantee prizes for all participants whether they win or lose. Draft Mode mixes things up a bit by pitting players against each other as they buildup their decks with randomly selected cards, with the incentive being that they get to keep all the drafted cards. New cards are also available, naturally, as well as a new Daily Rewards system. Lastly, SolForge has been made Universal, so it's no longer restricted to iPads and PCs. And of course it features cross-platform support, so you can access your game and account from any of your devices.
