Its a good mix of strategy and luck(rng or random card generator). The gameplay loop is fun. You can get the heroes and bases and their upgrades, without spending real monie. Not excessive grind, just the right amount. Whatever microtransactions present, are too pricey. The gameplay loop might wear soon. Overall, 1. Pretty graphics and character and animations. 2. Nice enough game mechanics not too strategic, sometimes heavy on luck. 3. Microtransactions are costly as heck.
