My anti-lead. In my experience, it beats nearly all leads. For those that it doesn't (Swampert, Bronzong, and a Heatran), my team has an answer for. 224 Speed lets me outspeed standard Magnezone, among other things. Usually, I kill my opponent's lead while they get rocks up, then explode on the 2nd pokemon. Occasionally, I'm able to kill their 2nd pokemon normally and explode on their 3rd.

Stealth Rock
Gyro Ball
Earthquake
Explosion
I was looking for a pokemon that's good at getting rocks up when it's not used as a lead, and I ended up with this. I tried out Skarmory and Forretress, but their lack of good Special Defense was hurting.

Breloom @ Toxic Orb
Poison Heal
Adamant (+Atk, -SpA)
EVs - 12 HP / 252 Atk / 244 Spe
Spore
Substitute
Seed Bomb
Focus Punch
Good at beating stall, which is nice for the current metagame. Absorbs statuses that Heracross doesn't want, which is really only paralysis.

Heatran @ Choice Scarf
Flash Fire
Naive (+Spe, -SpD)
EVs - 252 SpA / 252 Spe / 4 Atk
Fire Blast
Earth Power
Dragon Pulse
Explosion
My special-attacking scarfed pokemon. Fire Blast kills most things that don't resist it if they've taken some previous damage. Explosion is an excellent move to have on any pokemon.

Heracross @ Choice Scarf
Guts
Adamant (+Atk, -SpA)
EVs - 252 Atk / 252 Spe / 4 Def
Close Combat
Megahorn
Night Slash
Stone Edge
Not much to be said here. Close Combat beats a lot of stuff. I rarely use the other 3 attacks, but they can be helpful at times. Any suggestions for different moves?

Salamence @ Lum Berry
Intimidate
Naive (+Spe, -SpD)
EVs - 232 Atk / 24 SpA / 252 Spe
Dragon Dance
Outrage
Fire Blast
Earthquake
Switches in against anything that can't OHKO it and DD. Lum Berry keeps it going after Outrage confuses it. Salamence often lasts until Outrage is over, and it's confusion usually ends up killing it, so I prefer having Lum Berry over Life Orb.
