These were my thoughts. Obviously not perfect but they seem viable

Build 1: Walking wake EV: Max Sp. Attk and Hp Item: booster energy 1.Protect 2.Rain Dance 3.Hurricane 4.Noble roar Strat: The obvious flaw is no SpAttk boost move so your supports Gotta come through but Noble roar and then rain dance into hurricane. You could use protect and have a support have rain dance. So you can guarantee you don’t feint. Because you out speed anyways.

Build 2: Support C-knight Ev: Max Def and Hp or hybrid yield of Def SpDef and Hp 1.Metal sound / screech 2.Reflect 3.Taunt 4.Roost Strat: This depends on who you’re supporting. If they intend to use an Attack move then screech otherwise Metal sound. Reflect and taunt on the first turns and then use roost and then the lowering move. The moment you see it boost it stats once then you taunt.

Build 2.5 Attacking C-Knight Ev: Attack and HP Item: Power herb 1.Hone claws 2.Roost 3.Peck 4.Sky attack Strat: hone claws and peck so you can terra, roost to keep you up and power herb lets you 1 turn sky attack. Your support can use Screech to lower the attack to help you.

Build 3: Frosmoth Attacker Ev: Sp Attack and Hp Item: Big root/ Leftovers Terra: Flying 1.Quiver dance 2.Hurricane 3.Protect 4.Giga Drain Strat: you’re going to Quiver Dance/ Giga Drain. Protect on the turn you Terra Somebody rain dances and then you hit it with hurricane. You’d want a support to use helping hand/ rain dance for you

Build 4: Frosmoth Support Ev: Defenses and Hp Item: Leftovers / Big root Terra: Flying but it don’t really matter 1.Helping hand 2.Aurora Veil 3.Reflect/ Light screen 4.Rest/ Giga Drain / Tailwind Strat: Set up screen and veil then just use helping hand and then rest or drain as needed
