[REQUEST] Want to build a team with Metagross

[LuxKaos]

I was poking around Pokemon Home for awhile and happened to come across an old gem I had sitting around collecting dust for awhile - a shiny Metagross that I'm... not entirely sure how I came by but it's one of my old favorites nonetheless and I would love to feature it in a decent-ish team. Only problem is, I've kinda been out of the battling crowd for a while so I'm a bit rusty and am having some difficulty making up my mind for Metagross's partners.

Any ideas? I'd love to hear them.
