>>57404659I've got a strong Taupe team too, BFS Typhlosion, Charizard, Ninetales, and this Gentle Entei with Skill Trigger M and Helping Speed M.
Don't have a 5th fire type to add but would run my Wiggly instead.
The rest of the team is still sub-40 though, but boosting them and doing a prep-week like you had, yeah I could probably hit Master 20 at Taupe too.
I mean I'll eventually go back to Taupe for wringing out sleep styles, but it's gonna be a while. OGPP is my current focus.
