Hello, council member here, I know you're the Latios enjoyer so try giving this Dragon's Maw Latios Team a go, Static Tusk's there to slow down Roaring Moon and punish u-turn and the rest are just there to pivot in Latios, enjoy :D https://pokepast.es/16327b67b8fc87b4
Just look at the difference, that set wouldn't have done jacksquat vs this Sun but this set did so much!
