Very fun game. The characters, story, and battle mechanics are very well done. The only issues I have is that prism lens are scarce and difficult to obtain as far as I know making it harder to get animated cards for 5 star characters. I didn't like that everything is locked behind your commander level. Its a tedious thing to have cause I enjoy upgrading my characters. Also hope to see a balance of male and female characters added to the game. Overall great game and would recommend to anyone

The game is fun to play, ngl. However, as the season progresses, it felt like if you don't pull the banner unit, you would not be able to participate in the game events. The events are all gear toward the mechanics of the new units of the season. Especially in the weekly seasonal bosses. Also, the time it take to even build any units is ridiculous.

I have changed my review to 1 Star, because I can no longer play. the last 2 updates/patches simply don't load when I open the game. I tried rebooting, uninstalling, being patient. It just sits on the patching screen at 0 until it force closes itself. Not your typical card game. It is actually really fun, cool skills, beautiful animation, actual strategy involved. Unique and interesting storyline, not just some generic junk.
