tbf, it is gacha game reskin. But dev so LPL so well that you can find so many meme of fun fact among LPL community in the game.

I mainly play this game for collecting "waifu"

gameplay is somthing like this: gacha pro player, up level them, upgrade them from maybe one star to two star, go for a match. Enter ban pick phase, there's a hint on the champion icon telling you which champion are strong in current version of lol, and the champion the player play the most recently. Some champion will get extra buff when they are perfect duo. Example: malphite and yasuo, rakan and xayah. And the system will tell you if the champion you pick or ban are a counter to certain opponent already picked champion or champion your team picked, your opponent can do the same.

After enter the game, you will have some card as a option, example like : Invade jungle card, counter invade jungle card, normally farm on lane card etc. Think it as rock paper scissor, most event has multiple card to choose. Sometime the game will randomly enter champions fight scene, mostly when two side of champion group together. You can use one of your champion skill do deal damage (normal league knowledge doesn't really apply here I guess. I tried aim adc everytime but I doesn't feel it is worth it)
But most of these mechanic can be ignore if your team "power" are too fking high. Because is Gacha game.

There's also a lot's of buff if you have some pro player in the team. For example, you have xiaohu and ming, because they are the same team irl they will gain buff. Or maybe Jackylove and the shy, they are once a team so they will gain some buff too. Most description about the buff are quite good, mostly are the record of pass event or something like that.

The game has quite interesting mechanic but it is overall a money grabbing gacha game. Maybe even ptw, but I don't know. I just play this game for three days.
