Something like this came to mind. Whimsicott gets access to Tailwind so Golduck can actually be fast enough to Encore Xerneas before getting OHKOd with prior chip damage plus Worry Seed cancels out other weathers so you don't need to rely on Golduck in every game. Endeavor does a decent 40% to each Primal in the game at full HP plus if you're down to your sash, that pulls them down to 1% HP as well. Kyogre under Tailwind is a threat with Water Spout. Ferrothorn for opposing Kyogre, Xerneas, etc plus it has key resistances and Salamence for fast offensive support and an option against Mega Rayquaza as well as the other dragons in the meta such as Palkia, Zekrom, Hydreigon and Kyurem-W

Haven't tested out this yet, so I'll leave that to you

If needs be, create more diverse spreads. At the time of posting this, I was in sort of a haste so I didn't have the time to run calcs and EV each Pokemon properly
