What is the best moveset for a Metagross in D/P?

Question

I'm trying to figure out the best moveset for my Metagross in D/P, mine knows Hammer Arm, Meteor Mash, Bullet Punch, and Zen Headbut, and I've been looking for different moves to teach it because Metal isn't super effective against much, but I can't find anything...any ideas? My Metagross is EV trained in Attack and Speed, so all Special Attack moves are out of the question!!

Answer 1

Meteor Mash, Psychic, Sludge Bomb and Earthquake

or maybe Gyro Ball because metagross is slow

Answer 2

psychic(zen headbutt is great too), earthquake, ice punch, and explosion in case he almost dead.

Answer 3

great move set. although im still wondering if physic is better becuz of accuracy and power but metgrosses attack is higher but still u moves are fine the way there are. and there the sam as mine metagross too.

and try teaching moves like stone edge, giga impact, earthquake, ect
