Primal arceus or Xerneas

My current team is mega rayquaza delta draginight primal regigigas darkrai primal groudon, so what do you think would be better

Primal Arceus is busted as hell, but you already have a dragon, so meh. I would say get arceus and replace rayquaza.

arceus primal is a beast : safeguard, sword dance, extreme speed, return or eartquake or shadow claw adamant or jolly.

Im pretty suprised the fourm is so active, thanks for the feedback
