I figured some of the Platinum threats can be countered with the addition of a few BLs like P2, Donphan, and Moltres (damn that's 1/2 my team!). The reason being their Stats, typing, and exclusive movesets.
Here is my shot at countering many OU Platinum threats, don't hestitate to respond.
Porygon2 @ Leftovers
Modest
240 HP / 164 Def / 12 SpA / 92 SpD
-Ice Beam
-Discharge
-Magic Coat
-Recover
Strong lead, serves as an Anti-Status pokemon thanks to Magic Coat.
Trace allows it to counter Gyarados, Heatran, Gengar *Magic Coat Hypnosis + Immunity to Shadow Ball, Flygon, Jolteon, Salamence, Vaporeon *Magic Coat bounces back Toxic versions, and even some Rotom that don't use Rest *Immunity to Shadow Ball, bounces back W-o-w/Thunder Wave, and due to Rotom not having a reliable recovery move, Porygon2 can simply outstall it. Also counters Hypnosis/EQ Bronzong by copying Levitate with Trace and sending Hypnosis right back at it, plus since P2 is slow, Gyro Ball wont be doing much...
Forretress @ Leftovers
Impish
252 HP / 6 Atk / 252 Def
-Stealth Rocks
-Rapid Spin
-Toxic Spikes
-Explosion
Sets up SRocks, Toxic Spikes, spins away Rocks and Explodes.
Zapdos @ Leftovers
Bold
252 HP / 220 Def / 36 Spe
-Thunderbolt
-Hidden Power [Ice]
-Heat Wave
-Roost
Ice is covered with Vaporeon, and Donphan's Ice Shard.
Counters Vaporeon, Scizor, Heracross, Breloom, Metagross, Lucario, Skymin, Gyarados, and Gliscor.
Heatran@ Leftovers
Bold
4 Atk / 252 SpA / 252 Spe
-Fire Blast
-Earth Power
-Hidden Power [Ice]
-Explosion
Counters other Scarf/Specs Heatran, Scizor, Skarmary, Weavile, Dusknoir, Spiritomb, etc. Even Blissey.
Vaporeon @ Leftovers
Bold
188 HP / 252 Def / 64 SpA
-Wish
-Hidden Power [Electric]
-Surf
-Ice Beam
Water Absorber, and takes Ice Beams for my Donphan and Zapdos. My generic team healer.
Counters Gyarados, and numerous others like Heatran.
Scizor @ Life Orb
Impish
176 HP / 100 Attack / 176 Special Defense / 56 Spe
-Bullet Punch
-U-turn
-Pursuit
-Roost
Hits, Heals, and scouts (U-turn).
Takes Grass, Bug, Dragon, and Ice attacks quite well.
Overall 4/6 of my Pokemon know a recovery move, and have key Resistances/Immunities. They support each other with Wish, Rapid Spin, and each serve their own purpose. Basically they are all worth a place on my team.
