Hey Jam,
I had made a previous Mega Pinsir team you used in one of your lives. Built another team around bulky Volcarona and Serperior which can take on most of the metagame including stall thanks to sand and toxic spikes combined with sub-leech seed on Serperior. Koko lures tang and venu and kills with Fliynum Z for Serperior.

I'm confident in that I can be a decent builder in the tiers that I have interest in, so i took a step ahead and created this Ubers team: https://pokepast.es/103b3298240a7bbb
Mega-Swampert is one of my favorite mons, and seeing you use some heat OU pokémon in Ubers made me want to bring to this Legendary tier!
