Based on the users' reviews, here are three cons and pros of the app: **Cons:** 1. "Too many ads and in-app purchases, very annoying and distracting." 2. "Lack of game modes and features, gets repetitive quickly." 3. "Some levels are too hard or too easy, not challenging enough." **Pros:** 1. "Addictive and fun gameplay, easy to learn and play." 2. "Good variety of cards and characters, keeps the game fresh." 3. "Simple and intuitive design, easy to navigate and play." Note: The reviews are based on the Google Play Store reviews of the app at the time of my knowledge cutoff.
