The team lacks speed control and imo struggles against z-lovely kiss Jynx, Skuntank, Oricorio-Sensu and Kangaskhan. Dugtrio-Alola is able to outspeed and revenge Jynx, Skuntank and Oricorio, and provides a steel which although isn't bulky, is still able to pivot on fake outs to threaten a weakened Kanga. It can also lure in common switch ins such as Gastrodon and Palossand and memento into Lilligant to allow for a free set up. The team supports Dugtrio-Alola by having reliable switch ins to it's checks, Palossand for fighting types with mach punch such as Gurdurr and Hitmonchan and Clefairy for water types who come in once locked into iron head.
The biggest and most immediate problem facing this team is that it is a balance team lacking a way of stopping SS Carracosta. To help counteract this I chose Poliwrath as the last. Special Poliwrath gives an incredibly solid Carracosta/Kabutops answer,a mon with a decent matchup vs Skuntank which also gives the team issues, and one more fire switch in for the likes of z move Magmortars and Specs Pyroar making it harder to decide what move for it to lock into. Toxic wears down common switch ins like Lanturn as well as putting opposing Lilligant on a timer so Skunk/Clefairy have an easier time dealing with it. 176 Spe is for max speed neutral natured Abomasnow which can be obnoxious for the team do deal with.
