Maybe a strong team would look like:
Kadabra
Inner Focus
@Light Clay
-Psychic
-Taunt
-Light Screen
-Reflect
Psychic does 115.9% - 136.8% to 252 HP Machamp. Being able to blast that gorilla without the aid of a boosting move certainly makes Kadabra's situation here a lot better than the one Azelf faces in OU. Due to ridiculous speed for the tier, Kadabra might even be able to use modest. Monferno is the fastest SR user, and the Naive Ape comes no where near Modest Kadabra. With Inner Focus, Kadabra laughs at the Monkey's fake out, so unless Monferno is running Mach Punch as its priority, it has no chance. Taunt stops SR from slower users, and screens give Kadabra something to do.
Lairon
Rock Head
@Leftovers
-Head Smash
-Earthquake
-Substitute
-Stealth Rock
Awesome Edge-Quake coverage to be a threat after its used its decent resistances to set up SR. Essentially, you got to have something to stop those rampaging Gabites.
Seadra
Sniper
@Choice Specs
-Hydro Pump
-Ice Beam
-Surf
-Toxic / Hidden Power Electric
Seadra has no Swift Swim, so Sniper it is. Have you ever tried Specs Kingdra in OU, than you know the awesome power of such a set. Seadra has the same speed and special attack stats as Kingdra (95 sp.A, 85 speed)-- something I was not aware of. Albeit you lose STAB dragon attacks, but Hydro Pump and Surf provide more than enough awesome coverage. Without too many enemy water types to worry about (and enemy Seadra lacking the S.DEF to switch into this) Water/Ice Provides essentially flawless coverage. Toxic gives you filler to use should your enemy actually have a Sealeo or Poliwhirl. On an interesting note, Modest Sniper-Crit Hydro Pump does 85.2% - 100.3% to 0HP/252S.DEF Calm Chansey. Against Bold, you have more than a 50% chance to 1hko.
Poliwhirl (Or maybe go with the Magmar Belly Drummer instead)
@Salac Berry
-Belly Drum
-Substitute
-Waterfall
-Ice Punch
Speaking of Poliwhirl, if he actually did get a free turn he could probably capitalize well. With base 90 speed, it is blazing fast for the tier, and with Belly Drum and awesome Water/Ice attacking coverage, he could cause some serious ruckus-- especially if it gets screen support, or its potentialy counters get wrecked by Seadra. Kind of the "double dragon" effect. I also really think that Seadra would be insane, so this is a way to check it.
Gabite
@Choice Scarf
-Outrage
-Earthquake
-Stealth Rock
-Dragon Rush / Dragon Claw
Dragon / Ground has flawless coverage in the tier, Ground destroying every available steel type-- Lairon, Metang and Magneton. Therefore, Gabite has 2 extra slots to work with. Stealth Rock is here in case Lairon has difficulty setting it up, a serious danger considering its low special defense and 2 4x weaks. Gabites typing and speed can set up SR more reliably. Dragon Rush is useful early game when one does not yet want to get locked into Outrage. If the accuracy is a turn off, Dragon Claw is a possible alternative. Somewhat of a check against Electabuzz and Magmar as well.
Machoke
No Guard
@(so much potential shit)
-Dynamic Punch
-Payback
-Ice Punch
-Substitute/Bullet Punch
Just because it is awesome. Bullet Punch is extremely worth looking into, just because of the overall lack of good priority users in the tier. I also needed something to maul chansey . . .
tl:dr, do not mind me-- I just have another 2 and a half hours of hanging out at work with nothing to do. :/
Seadra sucks, simply, due to unimpressive speed, lack of swift swim, poor special attack in comparison with the rest of the game, AAAND lack of dragon stab, so it's an extremely inferior Kingdra. not worth running.
as for Pupitar, frail as shit, no sandstorm, has literally zero switch in chances. I don't see it doing well unless you come in on choice-locked normal attack, and most of those are still gouing to 3HKO.
I run Specs Sniper in OU, and 85 speed gets you farther than you would expect. How is it unimpressive? The only Middle Cup pokemon who outrun Seadra are (from the top):
-Kadabra 105
-Electabuzz 105
-Haunter 95
-Magmar 93
-Golbat 90
-Poliwhirl 90
-Vigoroth 90
And then out of those, the value of Vigoroth and Poliwhirl seems somewhat questionable . . . I would say 85 Speed would be atleast like OU's 100 speed mark, or maybe even better. The power of STAB Specs Hydro Pump / Surf is unquestionable I think. Water is the second best STAB, and while the dragons of Middle Cup are somewhat lacking in the raw offensive stats to abuse the lack of steel types, Seadra's 95 sp.ATK and Ice Beam is more than enough to rip shit up.
Well, again, theorymonning . . . theorymonning . . .
