>>31477953Unless your megaslot is already taken, you absolutely want Megagross. Honestly, Metagross might not be worth using without a megastone unless you really need a specific bulky steel with access to bullet punch that isn't Scizor for whatever reason.
A good moveset for megagross is something like
Meteor Mash/Iron Head
Zen Headbutt/Earthquake
Earthquake/Hammer Arm/Elemental punch of choice
Elemental Punch of choice/Hone Claws
I'm leery of Hone Claws Megagross. a turn of set-up for 1.5x damage isn't great, but then neither is 90/95% acuracy. I lean against it, because Megagross's biggest strength is how it can just come out and wreck shit unexpectedly.
Megagross is also fast enough to be a good user of Explosion. It can get Megagross an extra kill if it is about to die instead of just hurting something.
Pursuit is also a good pick if something else doesn't already have it. Putting damage where you want it is a good long-term strat.
Basically, Megagross works exceptionally as a revenge killer, a late game cleaner, a 1v1 tank spank and trade, or a wrecking ball to smash into a few pieces of a team. It's simple enough, but also very versatile.
>>31478341Honestly, going Max speed with some investment in both Attack and HP works very well. It really depends on what you want out of your 'gross. I personally prefer the bulk over balls-out power, but to each his own.
