Triple birds mon variation(Bulky Yvetel, bulky Ho OH and Scarf Rayquaza)

by red24246

Same theory as the teams Ive posted. Ho Oh gets decent defense so that it can withstand rockslide from a Gdon with it take a bit over half HP. It can recover HP when switched out thanks to regenarator plus being a decent tailwind spammer. Bulky Yvetel as well with decent defense and snarl to lower common special attackers like Magearna and Kyogre Primal. Arceus has safeguard as a precaution against sleep spammers like Amoongus and Smeargle. Can be switched out for Tailwind, Trick room,Will O wisp or even recover lol. Also scarf Rayquaza which outspeeds even most geomanced Xereneas that havent got much speed investment. Enjoy!!!
