It was really fun and engaging at first, I didnt even mind spending couple of bucks in the beggining, but this game seems to have a mechanic where it always matches you with higher power level players to pressure you into buying hero cards to upgrade your hero and purchase other upgrades. I stopped playing, because I got tired of playing with other players with waaay higher base stats - you get destroyed so easy, even with my best heroes. Not recommended if you're looking for long-term fun
