Started off really fun but then it comes to a point where the game is basically unplayable. Not enough resources to pull for better cards and no way to get gems unless you pay for them in order to advance gameplay. The fusion system kicks out the same cards over and over so no advancement there either. I really like the game but these issues turns a good game into a really bad one.

***Edit 3 - Everything was restored a few days later game has no issues. Dev team seems pretty active. **Edit 2 - Wiped all progress when I was allowed back in and no way to sync with old account. **Edit - No longer playable. Telling me ive played on a newer version and to download the newer version. tried to uninstall and reinstall and still not working. Pretty good. basic, but not riddled with ads and don't feel like it's just a money grab yet

It was a great casual game until the last update. The levelling progression was reasonable, if not a little easy. Instead of just slightly scaling up levelling costs alongside the bit of new content, It became a completely overscaled grind making ftp players almost incapable of ever leveling through even mid-game. Long-time players are bailing because the latest update turned it entirely pay-to-play.
