I think this is a little harsh. It’s a fun time waster and there is progress in that you earn better more powerful cards. There’s some strategy involved in picking the cards in your build, healers, etc. You can upgrade your cards to be more powerful. And you will need more attack power, better healing to succeed in harder tiers. I’ll admit it isn’t the deepest game in the world and probably would have worked better at a $2.99-3.99 price point. But the goal of getting to higher and higher levels and deciding when to leave takes some thought and progress with your build to achieve. It’s a time waster. But a polished, well made time waster. I don’t regret my purchase.
