I'm working towards building this team in-game, but only Volcarona is 100% done, so I'm open to suggestions.
Mamoswine
-Ice Shard
-Endeavor
-Earthquake
-Stealth Rock
Item: Focus Sash
Ability: Snow Cloak
Natue: Adamant
EVs: 252 Atk / 4 Def / 252 Spe
This seemed like a nice aggressive lead that can set up Stealth Rock, so...yeah.
Volcarona
-Quiver Dance
-Bug Buzz
-Fiery Dance
-Psychic
Item: Life Orb
Ability: Flame Body
Nature: Modest
EVs: 252 SpA / 4 SpD / 252 Spe
As I said before, this is the one I already finished training. I know Hidden Power would be nice, but breeding for the perfect IVs is a nightmare I don't want to get into. Volcarona is beastly once it gets one or two boosts in, not to mention it's an awesome little bug.
Scizor
-Swords Dance
-Bullet Punch
-Bug Bite
-Roost
Item: Leftovers
Ability: Technician
Nature: Adamant
EVs: 252 HP / 40 Atk / 216 SpD
What's better than a sweeping bug? Two sweeping bugs, of course! Scizor is beastly.
Hydreigon
-Draco Meteor
-Dragon Pulse
-Flamethrower
-Surf
Item: Choice Specs
Ability: Levitate
Nature: Modest
EVs: 64 HP / 252 SpA / 192 Spe
Hydreigon hits hard and helps absorb the fire attacks that are aimed at Mamoswine and Scizor. Not much else to say.
Vaporeon
-Wish
-Protect
-Scald
-Roar
Item: Leftovers
Ability: Water Absorb
Nature: Bold
EVs: 248 HP / 252 Def / 8 SpD
Vaporeon can absorb those water attacks that can be aimed at Mamoswine and Volcarona, and also provides healing to everything that needs it.
Conkeldurr
-Bulk Up
-Drain Punch
-Mach Punch
-Payback / Stone Edge
Item: Leftovers
Ability: Guts
Nature: Brave
EVs: 120 HP / 252 Atk / 136 SpD
So, to fill in the complete lack of fighting coverage, Conkeldurr goes in the last slot to fill in as a bulky guy. I'm not sure which of Payback or Stone Edge is better at this point, or even if Conkeldurr is a good fit for this team at all.
My biggest concerns with the set are the lack of speed on the team and the fact that I have 3 boosting attackers. I do like how bulky the Pokemon on this set are overall, though.
