Needless to say, I'm definitely not a pro at any of this yet, so I apologize if this team is terrible. However, I have about a 60% win rate right now, so I'm assuming that I have the basic idea down and that I just need some fine-tuning.
To start, I decided to use Infernape. I've been seeing lots of Metagross mentioned on the RMT lately, so I wanted something to anti-lead it. Ironically, I have yet to see a metagross lead :-P
Next, I took the whole "USE SYNERGY GRAAAGH!" advice to heart and started looking for some pokemon to compliment Infernape, and I came up with Scizor.
Next I moved on to "What synergizes with Scizor?" and added in Tyranitar, who also doubles as a synergy for Infernape. Vaporeon was also suggested, and since I've always like Vaporeon anyway, I threw this one in as well.
I noticed a lot of love for Rotom-H on the forums, and having used him, I can see why he's so darned popular. Rotom-H pairs VERY nicely with both Tyranitar and Scizor, so my interest in Rotom was confirmed through them working together.
I was at a total loss for my sixth pokemon, so originally I had latias. However, at the suggestion of people here, I switched to Machamp. These previous five are very stall-weak (something I had been looking to address), so I'm testing Machamp now to see if he helps at all.
So there's my rationale. Now for the in-depth.
Lead Infernape
Infernape @Focus Sash
Naive 64 Atk / 252 SpA / 192 Spe
~ Fakeout
~ Stealth Rock
~ Fire Blast
~ Close Combat
Basic setup here- I start with fakeout to get a quick bit of damage, and then I set up stealth rock. From there I usually wind up getting taken down to 1 HP, at which point if the other lead is slower, I'll use one last fire blast/close combat on my way out. If the lead's faster, I'll pull him out and attempt to get a wish in somewhere to heal him.
I lean towards suiciding this guy to get my stealth rock up. Again, except against faster leads (and swampert), I'll give a parting gift, which has gotten more OHKOs than I would have originally expected.
CBScizor
Scizor@ Choice Band/ Technician
Adamant 248 HP / 252 Atk / 8 Spe
~ U-turn
~ Bullet Punch
~ Superpower
~ Pursuit
I always said I'd never use Scizor because it's the very definition of "OU," but the darned thing just works with pretty much everything else I'm using, which really leaves me no options, does it.
Again, standard set. Pursuit to deal with ghosts, superpower to deal with blissey, U-Turn to scout, and bullet punch on the rest. He serves as my primary dragon counter, and while I have Latias in the back of my team, I typically leave Scizor to do the heavy lifting on that sort of stuff in order to save Latias for later.
DDTar
Tyranitar@ Babiri Berry
Adamant 4 HP / 252 Atk / 252 Spe
~ Dragon Dance
~ Fire Punch
~ Crunch
~ Earthquake
As he's used now, he's a potential sweeper. I'll switch into something and if it's a pokemon I can scare out I'll dragon dance and then smack the other pokemon around. Crunch for absurd STAB, while Earthquake was a given- that's my ONLY EQ user on the team. Babiri/Fire Punch have netted me several Scizor KOs, which as was pointed out is one of the things this set really has going for it.
Wish Vaporeon
Vaporeon@Leftovers
Bold 188 HP / 252 Def / 68 Spe
~ Wish
~ Protect
~ Surf
~ Roar
Bulky Waters have always intrigued me, and Vaporeon has been an interesting pokemon to use. I originally had HP lit on this guy, but he wasn't doing too much for me that way, so I switched that over to Toxic. This worked great, but it was suggested that I try roar instead. Given that I always put up stealth rock immediately, roar probably does more for me than toxic would do anyway. Not to mention I get a phazer, which I definitely need.
Rotom-H (Standard)
Rotom-H@Leftovers
Bold 252 HP / 68 Def / 188 Spe
~ Discharge
~ Shadow Ball
~ Overheat
~ Will-O-Wisp
This guy has been awesome for me. Between will-o-wisp and discharge, I get to status people like crazy with this guy while overheat just destroys things. Shadowball nets me some surprise KOs if I decide to stay in against ghosts and psychics.
The EV distribution allows me to outrun Adamant Lucario, which is a pokemon that I have not seen yet. I can't really comment on how well this works until I actually am up against one, but hopefully it proves very beneficial.
Machamp
Machamp@Leftovers/ No Guard
Adamant 248 HP / 252 Atk / 8 Spe
~ DynamicPunch
~ Payback
~ Stone Edge
~ Substitute
I hate fighting Machamps, so I am very excited to add this bastard to my team. Bring him in on anything weak to dynamicpunch and sub on the switch. From there I can payback rotoms and dynamicpunch most anything else. I just made the switch, so I'll post more details about what this guy can do when I get a chance to test it.
Thanks for all of the input!
