Hey I know this is a bit late, but about my Duggy team:
Well tbh, it sucks lol. That was just my 3rd team and I didn't know teambuilding that well at that time. It also has no synergy at all, at I have trouble against a lot of mons. Duggy feels like dead weight most of the time -- I finally realised why no one uses it. It just doesn't justify a spot on the team.

Here's the team again btw, if you wanna modify a few things and use it then feel free to do so!

Here's another team I made yesterday (which I was using against alchemist in that match you joined, I had to leave that in between :cri:). Its CM Steelceus + Band Ada M-ray. I chose Steelceus cause I tried Groundceus before and its worse enemy is toxic, which steelceus doesn't need to worry about.
I played a lot of games with this team today and got about 20 wins with just 2 or 3 loses (one of them was against a team with 5 extreme killer normalceus :x) and got from around 1600 to 1801. :)
