Yo Blunder, Toga Khan here,

This is an extremely strong Mega Sciz Webs, literally. I run this because Bulky Roost Sciz really got hurt with 8 PP Roost. I got Serp, SD Pads Urshifu, SD Ledge to help him vs Waters, Fires. I run Thund T as it answers all Electrics, Ground Immunity and Taunt for Defog, with Serp in back, you can easily prevent Fog.
The issue is that I feel that this team style is not that suited in SV OU. Teams like this work in NatDex but not in SV OU because it's so centralized around hazard offense + Regen+Pivot mons.
