This game actually has a very fun battle system that changes Pokemon battles from the traditional turn based system to that of a timed-energy system, and all battles are 3v3 with designated Strike, Support, or Tech class Pokemon.

Unfortuantely all of those positives are ruined by mobile game mechanics. Endless upgrades, repetitious events that require you to play the same battle a hundred times, and way too many characters to actually have any sort of balance. At least half the roster is literally unusable and has no scenario in which they would be worth picking over another character. There are options for increasing the power of moves like repeated pulls and more, but that is really only useful for Strike characters. Increasing power is basically useless for Tech and Support classes because their value doesn't come from raw strength.

I've got pretty much every character to their max level so I just play the hardest battles which are either too easy or too hard, there is no in between.

I'm pretty bored of playing the game at this point and have mostly stopped. I occasionally play it for a week or so when they have an event going on. But it's really come down to just a collecting-fest. Barely any substance anymore.
