Fun game when it work but this game will troll the living hell out of you. Extremely bad RNG. You will go on 10+ pvp game losing streaks just because the game decides to give you units you don't need one after the other. What's the point of having any kind of strategy using the units you have. I've also noticed when you don't spend RNG is worst. When you buy their pass, RNG is more manageable. And pvp mode is the only mode you can play after you use the 3 keys in co op dungeons.
