Honestly, the fairness of matchups feels balanced in most cases, though I occasionally face opponents who seem over-leveled compared to my cards. The timers for turns keep the game moving and maintain excitement, but they could be a tad longer for players who enjoy thinking through strategies. I've encountered a bug that occasionally freezes the app, requiring me to close and reopen it. The variety of game modes keeps things fresh, yet I would like to see more customization options for my cards. Overall, it’s a solid card game app with room for improvement.
