Looking back onto that match I had done lots of misplaysSwap Victini on Volcarona and click V-Create. Beats every set other than some really odd ones. As for no removal being too punishing, just utilize Clerable to prevent Tapu Koko and Victini frim getting their items Knockrd Off and it should be OK. You'll definitely want removal sometimes, but often stacking up your own hazards is better than removal.
Did a couple dozen battles and the only match I faced difficulty against other than near complete ele/move counters where surprisingly against a Gengar. It just sweeped the entire team one by one TvT after it had chipped away a bit of all of their healths using various methods.
Probably had choice specs idk.
