I actually have access to someone who can change the pokeballs of pokemon, so I'll end up having him switch my Beldum's pokeball. Thanks for all of your input!I've got a flawless jolly male charmander in repeat ball if you want it VM me. It's free.
Metagross: Dive, Net, Great
Kabutops: Luxury
Metagross is genderless and cannot pass down the ball you'll need to either RNG abuse one, SR it in the friend safari or trade with someone who has it.
