Mmkay, let's see. This is your standard Azelf Lead. It's been a favorite of many people for quite a long time. I've seen them used in nearly every battle, and because of this, many people pack a numerous amount of anti-leads. Now, there aren't a huge number of pokemon who can outspeed you, especially from the get-go. One Problem you may encounter is Trick-Scarf Leads. You go for rocks, and get stuck with that move. Thankfully though, Azelf can switch out and abuse it's new found speed later on. Watch out, Tyranitar completely obliterates you. Resists two of your attacks, and is immune to the other. A well placed Pursuit and your gone.
So your going for the Jolteon and Gyarados Offensive Core. With near Perfect Synergy, not alot can get in your way. The problem with this Core though, is Skarm Bliss completely walls it. Not only that, but a Skarmory vs Heatran can start juggling your team around with Whirlwind. Of course it will switch to Blissey as soon as you get back to Jolteon, but it has already scouted many members of your team, and putting you at a disadvantage when it comes to playing mindgames. I see you have Mixnape later on though, so this weakness is covered.
Your standard DD-Dos. Might I ask why you choose Bounce? It's a completely terrible move, it takes sero prediction for your opponent to bring in a counter. I reccomend Ice Fange, nearly the same coverage, handles the likes of Gliscor better, and has better accuracy. It even has a Hax factor to help with it's lackluster power, even though with enough DD's you'll be all set.
I have used Agilisubpoleon on numerous occasions, and it is quite the effective sweeper. Keep in mind though that you are walled by most any bulky waters, such as Vaporeon or Suicune (Especially the latter in the form of CroCune) I would reccomend squeezing Grass Knot on there somewhere, if you ditch Sub, I reccomend going with Life Orb in it's place.
Okay then, more or less your standard Gengar, you really should be using ScarfGar or Specsgar. Trust me when I say that the little extra power/speed is very much needed for Gar. Exploding is fun, but watch out for enemy ghosts, they can ruin you, if they are scarfed (and you aren't) you'll be in for a hurting. A relatively nice pokemon though, especially with it's good coverage.
Well this guy is commonly seen on Hyper Offense teams. You always want one mixed attacker, and Infernape is one of the best. I have zero complaints about this particular pokemon. Watch out for Gliscor though, it might not be faster, but it can survive a hit and KO you with Earthquake.
I noticed some minor errors. Such as Offence (Pretty sure it's Offense), and Kamakazi (Actually Kamikaze [Kah-mee-kah-zay] Japanese for "Divine Wind") On a pokemon related note, It would almost seem like you've missed some crucial aspects of Hyper Offense. Where is your Choice Scarf Pokemon? as well as a Choice Band. You should have one of each if you are running Hyper Offense, the entire point is to Obliterate your opponents as fast as possible, without giving them the chance to do anything in return. It feels like you might have missed that point, otherwise, it's a good team, just not quite Hyper Offense.
A few notes to remember also, is that you have no priority moves. This will severely dampen your chances for success if you opponent manages to set up a sweep. I believe it takes gyara only 1 or 2 DD's to outspeed your team, and run right through it. To rectify this, at least in part, run a good priority abuser like Lucario or Scizor. I think that's all I have to say about this team. Also, to help with the team rating process, it hellps to include lengthy paragraphs on how the pokemon fights, as well as many scenario's it's been in, it shows us you've actually battled with it, and you will also be able to tell us it's weakpoints, for fixing.7/10
