Hey, I don't want to clutter the Teambuilding Workshop thread with non-request/team posts so I'll respond here:
Sun is inherently a janky and extremely matchup based playstyle and the decisions I made with the team were designed to provide as much pressure as possible given the constraints of using a sun team + chlorophyll sweeper. I'll just address the stuff you asked about in order:
1. Venusaur is super weak so modest is absolutely necessary (Sludge only does like 60% to Latios for example which is Venu's best way of hitting it no way in hell can I fit Pursuit support on a sun team)
2. Sun is up a ton because other weather is rare and Torkoal pivots into a surprising amount of things so I can afford to run Solar Beam (I'm also largely just copying what TDK ran on his sun HO); again, Venu is super weak so I feel like the extra power of Beam is necessary as well.
3. I actually never had the opportunity to use EQ or Growth in my testing so IDK about that; honestly Dugtrio is pretty hard to trap a decent player's Tran with, so I'd just use EQ for the sake of RKing Gengar.
4. The Def investment + nature hits a jump point so I just dumped some into SpA for a slightly harder-hitting Plume. You could easily just run max HP max Def but idk. Doesn't really matter.
Look, I know that we don't know each other, but, can you add my Friend Code??
