This is a portrait-oriented, asynchronous online card game that can be played in short sessions and is highly interruptible. While it offers high replay value and can be played one-handed, its monetization is pay-to-win, with an energy system that limits play and encourages spending. It's best suited for players who enjoy competitive card games and don't mind the aggressive monetization model.
