How to get 300-1000 Attack on any pokemon in 1 turn:
Medicham
Pure Power
Focus Sash / Leftovers
128 Def / 128 SpD / 252 Hp
Protect
Seismic Toss
Recover / Detect
Helping Hand / Light Screen / Fake Out
Medicham's job is just to survive the first turn.
Pick a pokemon which learns Skill Swap. On the first turn, swap with Medicham. The pokemon that gains this skill gets 2x their attack stat.
<Notable Pokemon That Learns Skill Swap with Max Nature'd Attack>
Allakhazam - 218 x 2 = 436 Attack
Azelf - 383 x 2 = 700~ Attack
Banette - 361 x 2 = 650~ Attack
Blissey - 130 x 2 = 260 Attack
Bronzong - 304 x 2 = 608 Attack
Butterfree - 207 x 2 = 414 Attack
Celebi - 328 x 2 = 650~ Attack
Deoxys - 438 x 2 = 900~ Attack
Deoxys-A - 504 x 2 = 1008 Attack
Deoxys-D - 262 x 2 = 500~ Attack
Deoxys-S - 317 x 2 = 600~ Attack
Drifblim - 284 x 2 = 600~ Attack
Dusknoir - 328 x 2 = 650 Attack
Exeguttor - 317 x 2 = 600~ Attack
Jirachi - 328 x 2 = 650~ Attack
Gallade - 383 x 2 = 800~ Attack
I was going to list them all, but the basic idea is to take a pokemon and either give its mediocre attack power a significant boost, or to take a pokemon heavy in attack power and make it insanely destructive. Medicham becomes a useless support pokemon, but if you can get a Deoxys with 1000 normal attack power... you could extreme speed everything into oblivion. A Butterfree with 400 attack power is pretty scary. Give em' a life orb and some speed and you can make almost any pokemon a physical sweeper.
I've tested this with Gallade and it works, you can skill swap an ally and it will function perfectly. I haven't tried skill swapping with Medicham protecting, however, so you may want to replace that skill with Fake Out or Helping Hand if he doesn't already have that. Protect / Detect are excellent for stalling though.
I haven't tested this, but you could also switch Medicham out after Skill Swapping, then you could Skill Swap AGAIN and give a pokemon that can't learn Skill Swap Pure Power (like Tyranitar or Aerodactyl), it would take longer to set up, but could be even more devastating.
*After consulting with my brother I suppose I'll have to test this again. Although I did test Medicham/Gallade it was a while ago, I still do believe you can skill swap an ally, but I'll test it again to make sure.
You can Skill Swap an ally. However, Skill Swapping either Pure Power or Huge Power only gives a x1.5 boost. Thus, all your Math is wrong. Physical Alakazam is stupid. The only pokemon this is worthwhile for is Gallade.
Torkoal
Leftovers
White Smoke
252 Def / 200 Hp / 52 SpD
Amnesia
Sleep Talk / Rapid Spin / Stealth Rock
Rest
Lava Plume
You could drop the EV in SpD for some SpA or Hp however it's imperative that Torkoal survive a few turns with his base SpD stat.
Combined with:
A Pokemon that learns Flash Fire such as:
Heatran
Flash Fire
Choice Scarf / Life Orb
4 Hp / 252 SpA / 252 Speed
Earth Power
Heat Wave
Explosion
HP Ice / Fire Blast
The idea here is for Torkoal to Lava Plume with a Flash Fire pokemon out. It will hit both opposing pokemon and your ally, giving them 50% more power to fire attacks. Pretty basic, so it works with any build. Heatran is the standard CS Heatran except I reccomend having Fire Blast AND Heat Wave because while Heatwave is preferable in doubles, Fire Blast with its added power could OHKO things that Heatwave will not. You're going for fire attacks anyway, the other moves are just for double weaknesses.
Pokemon with good speed base are probably better with this strategy, such as Rapidash (who can Hypnosis) or Arcanine or Hounddoom (who can Nasty Plot). If you're going to use this stat, I'd recommend trying a fire monotype team for doubles – discovering that Lava Plume hits your ally inspired me to do just that.
This same strategy has been done with Toxicroak (Water Absorb and Surf) but it can also be replicated with Volt Absorb (Discharge from Zapdos or a utility pokemon like Electrode who has low SpA – the purpose of Discharge and Lava Plume is not to deal damage, but to heal the sweeper pokemon 25% hp each turn while burning/paralyzing the opponent [Discharge/Lava Plume have high chances of Paralyze/Burn]) and Electavire's Motor Ability [which gives him +1 Speed when hit by lightning].
If you have Torkoal and Heatran out, won't a turn 1 Earthquake KO both of them? Toxicroak+Surf and Jolteon/Electivire+Discharge are OK though.
Bronzong
Levitate
252 Hp / 80 Def / 92 SpD / 86 Attack
Trick Room
Safeguard
Swagger
Gyro Ball / Explosion / Hypnosis
+
Marowak
Rock Head / Lightning Rod
Thick Club
252 Hp / 252 Attack / 4 Def
Earthquake
Fire Punch
Swords Dance / Double Edge
Thunder Punch / Rock Slide
There are two ways to play this: Safeguard on the first turn (to prevent sleep), then Trick Room, then Safeguard, then Swagger Marowak (he will not be confused because of Safeguard) or you can Trick Room, then Safeguard, then Swagger Marowak. Basically, it makes Bronzong into a utility stat raiser, ideal for a trick room team. You don't have to waste precious turns swords dancing! Though you can, swiftly raising your attack and flinching with rockslide or double OHKO'ing with Earthquake.
*cough*no pokemon to prevent Taunt*cough*. Otherwise, good strategy, and I've seen it before in the Seattle VGC 2009.
