I just had my 84th trio game and moonbane popped at the end of the match. I legit thought it was a myth cause everyone says they had more than 200+ games and never saw it, also there is no video with it anywhere.
Unfortunately I have no video footage as well :(, but I just wanna let you know it's there.
Also it's not that hard to beat it, but you can't do it alone, your teammates must play their part too. Gl hf :)!
