Hippowdon @ Leftovers
Impish - Sand Stream
244 Defence, 252 HP, 12 Sp. Def
Typical Hippowdon lead, sets down Rocks, and Roars. Slack Off and Defensive bulk stops all physical attackers in their tracks, and Earthquake stops him from being Taunt bait.
Landorus @ Life Orb
Modest - Sand Force
252 Sp. Atk, 132 Speed, 124 HP
-Hidden Power (Ice)
Rock Polish Landorus outspeeds everything unscarfed and most scarfed sets at +2. Earth Power is his primary STAB, hitting anything that doesn't resist it hard. Hidden Power Ice hits flying types and Gliscor. Focus Blast hits Skarmory and Steel types for hard damage, including Air Balloon Heatran.
Mamoswine @ Life Orb
Jolly - Thick Fat
252 Attack, 252 Speed, 4 Defense
Typical physical Mamoswine. Ice Shard gets Priority and breaks Dragonite's Multiscale pretty well. Icicle Crash and Earthquake both get STAB, with Stone Edge to round off the coverage. Not too much to say here.
Flygon @ Choice Scarf
Naive - Levitate
252 Attack, 252 Speed, 4 Sp. Atk
Resurrecting one of DPPt's premier threats, ScarfGon. Earthquake and Outrage are both insanely powerful STAB attacks, coming from someone who outspeeds almost the entire unboosted tier, bar Ninjask. Fire Blast hits Skarmory harder than anything else on the team, 2HKOing it easily. U-Turn for scouting.
Gastrodon @ Leftovers
Sassy - Storm Drain
252 HP, 252 Sp. Def, 4 Sp. Atk
I've already got plenty of physical bulk, now I need some special bulk. Gastrodon fits the bill perfectly. Switching him in on a Water attack gives him a useful boost to his rather low Sp. Atk, and lets him hit that much harder with STAB Scald. Earthquake hits mons like Heatran and Tyranitar. Recover and Toxic kills everything that the other moves don't.
Donphan @ Leftovers
Impish - Sand Veil
252 HP, 82 Defence, 176 Sp. Def
Donphan spins for my team, and with Sand Veil and some Sp. Def EVs, he can tank some unboosted hits with ease. Roar and Toxic lets him spread status throughout my opponent's team. Earthquake stops him from being ****ed over by Taunt.
So... Yeah. That's it.
