Metagross Pursuit hits harder than Scizor Pursuit, assuming they switch out and Technician is not activated. Of course, it they stay in, Pursuit will be weak as shit either way so it doesnt matter anyway.
As I said, 4G move tutor, though it's illegal with anything in Gen5 (which I guess is just Hone Claws, but still...)
People, don't use Ice Punch on CB Gross. It's bad. Instead, you should just 2HKO standard Gliscor with Meteor Mash.
The OHKO is a big deal if don't want to get outsped and EQ'ed on the next turn, Ev's factor in here but I doubt you're surviving a STAB EQ from Gliscor. And if you're using Choice Band Metagross than it should be a Gen 4 version, Hone Claws+Choice Item=Lol
And btw, Conkeldurr and Metagross are both Bulky Physical attackers. Conkeldurr just does it better. The set up move doesn't always need to be the same for identical roles. For example, SD Excadrill>SD/RP Landorus>Rock Polish Rampardos (all physical sweepers). I go by general team roles, not specific sets.
@Woodchuck Ice Punch shouldn't be a KO w/o Choice Band, unless I need a new damage calculator (with my pokemon expertise, I do), but it also does great against Skarm and Bronzong, making them EQ weak and less reliable counters to your physical sweeper. Like Landorus, which doesn't need a Gliscor lure unless it's Scarfed assuming it goes mixed.
And Metagross has base 95 Sp Atk, why would use use something that slow and Mixed for Flash Cannon and Psychic, getting in that Agility isn't a given anymore, don't see the point.
