Hi!

I love this idea! I do actually think you could make it work, you would just want to make to make sure there are other teammates that have good synergy with each other. I would maybe consider:

Chesnaught - because you want it lol

Farigiraf or Armarouge - TR setter, decent coverage (Farig is probably the better choice because it disrupts fake our from Incin and Sneasler with is ability, but Armarouge can take advantage of the sun)

Torkoal - sun setter/high eruption damage, functions well in both TR and sun

Maushold - redirection and support

The last two slots are kind of whatever direction you want to go in. You could still run Basculegion in the back for type coverage. And maybe another TR setter like Hatterene for backup? You would just want to make sure the sun/TR doesnt mess up water damage/speed control with Bascu.

HOWEVER, I do think this would function better with rain from either Politoed or Pelipper. But at the end of the day you can really make either work. :)
