>>35279672I remember shinybirb to be way harder than shiny xern. Still kinda mad that I had to use two full item runs to get the S-Rank
My team was: Ttar 15 lv1, Silvally 20 lv5, Xern 20 Quirky+ lv4, Machamp 20 lv5
If I recall correctly I used Xern just for the high BP and not for quirky memes. And kek machamp. how time flies :^)
So your team should be decent enough. Or maybe you need another try
For your other question: the stages of most of the fully evolved shitmons are kinda annoying. like empoleon, torterra or whiscash. Also some stages can be hard depending on your memes, like Crobat without BB Groudon
