Lopunny forms a pretty sick Offensive core with Thundurus, as Thundurus can smash Clef / Venusaur / Celebi (and also dent Mew) with its coverage in HP Flying+Sludge and Knock Off, while Lopunny pressures murks Hippowdon @ +1, along with Tyranitar who checks Thundurus

Lopunny and Thundurus are weak to Pokemon such as Zard X, Excadrill, Garchomp, Metagross, Aero, Landorus (Scarf) and Hippowdon. SD Gliscor chips away at bulky Ground types, and beats non Aqua Tail / Ice Punch Meta 1v1. Also a fairly safe switch in to Sableye once the Orb is activated, and sets up on it since Foul Play does nothing

Next, we have AV Metagross. Better check to stuff like Mega Alakazam than Jirachi is because of Pursuit, and priority is great to have on Bulky Offense. Handles problematic mons such as Clefable, Diancie, Latis, Kyurem-B and Gardevoir. Forgot to mention it also better at dealing with Venusaur than Jirachi is

Weavile, Keldeo, Manectric, Mega Gyara, Starmie (Gross doesnt take Analytic Pumps well), Lopunny were all still very threatening to the team. Also had no rocks, so I finished it off with the two mon core of SpDef SR Celebi+Scarf Keldeo. Celebi of course dealing with the likes of Keldeo, Manectric, Starmie and switching into Lopunny to an extent. While Scarf Keldeo deals with Mega Gyara, Weavile and Lopunny. U-Turn is used over BP on Celebi because you don't want to be in a situation where you need to BP out into Keldeo / Thundurus, but have a -2 and they're significantly weak. U-Turning on an incoming Hoopa is probably the most hilarious thing

Other: 4 HP on Thundurus gives it an odd Hp number for less damage on rocks switch ins, burns and toxic damage. Speed on Gliscor outruns base 70s. Speed on Gross outruns zero speed Venusaur
