you should thank those people for pay for the game SO YOU DONT have to spend cash but still get updates and an active developer... just level up your chars and stages... gives more than enough gems to build at least 1 KoG-deck... if you spend your gems left and right rather than focus on a meta you never will get far...
Another moron who beleives that game devs should work for free. And worse of all, is that also took the opportuniy to ask for a massive blowjob. What a 🔥!
