guaranteed OHKO
Generally, I've found that Metagross likes to play more defensive roles with items like Assault Vest to maximize its total bulk. It naturally hits like a truck as well, let alone with full investment. Electivire seems to be the main setup sweeper out of the three, with a double sweeper set of Bulk Up + Trailblaze with Supercell Slam and a coverage move (
usually Ice Punch). Here's a set I've been tooling around with that's more Utility Attacker
Electivire @ Expert Belt
Ability: Motor Drive
Shiny: Yes
Tera Type: Dark
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Supercell Slam
- Ice Punch
- Knock Off
- Trailblaze
Magmortar got Knock Off as well, so Magmortar generally likes to run a nuclear offensive utility set as well - just with more of a focus on outright blowing through opposing cores as opposed to Electivire being a little more reserved.
