Some kinda unorthodox stuff on here so I'll explain it a little.
Adamant Lopunny gives lots of teams an immense headache to the point that I kinda feel like it's beein built around here. It also makes picking off Mega Charizard X an easier job due to the extra power behind Quick Attack/Fake Out than Jolly Lop has, and the team doesn't really feel that weak to the stuff that Jolly actually achieves over it barring, like, Torn which eventually loses to double prio anyway while also being susceptible to both para and Volt Switch (not to mention Rotom p. consistently comes in on it).
HerbTran is there because currently the only way of consistently breaking fat waters is Latios. That said, you need to be aware that it doesn't beat VinCune. Rotom is p. standard so I'll just chuck it in here rather than giving it its own paragraph. I considered both fast Sitrus and double status but I think being able to recover and semi-consistently switch in on Torn is important on an ada Lop team. It provides a slow Volt Switch to get Latios and Lopunny in on stuff.
Clef is Bold 'cause fuck Weavile and LO+Psyshock Latios. It also has Healing Wish because why the fuck not. HW Clef is hella underrated so yeah it's nice to have in the back to heal something up back to full, and it's especially nice if you need Latios to take a hit from something, most notably helping with the Keldeo matchup. T-wave 'cause this team's speed control is ada Lop.
Lando provides a second slow U-turner while also dealing with the issue of Stealth Rock. I originally had Scarf but then I realised the team had no speed control+Rotom as the only slow VoltTurner for Lop/Lati so I swapped SR out for T-wave on Clef 'cause I like HW and gave this thing a helmet set. It's also nice because the team otherwise loses to sand and Zard X.
Latios is specs 'cause it's the best set. HP Fire is used in the last slot because when ur only way of breaking physically bulky Mega Scizor consistently is Tran (which it won't stay in on) then it's nice to have a way to bait it in.
Things I'm least sure on:
- HW Clef
- Ada Lop
- Pain Split Rotom-W
