A new Digimon Card Game app is currently in development by Bandai, creator of the popular trading card games such as One Piece and Dragon Ball. It will be called Digimon Alysion, a brand new online, free-to-play mobile based on the Digimon TCG featuring new "DigiAly" cards!
The trailer is currently only available in Japanese, but based on the images shown it looks to have both PvE (story) and PvP matches, but may not be the full 1:1 card game simulator from the tabletop version as the competitive players may hope. Instead, it could be a more simplified experience similar to Pokémon TCG Pocket that has shown massive success so far.
