Possible Team Retirement

This team is what came from me and Reverb talking about cores, we came up with one of Jirachi/MixNite/CBPert. This team has been succesful, but, there a some improvements to be made.


Machamp
Adamant @ Lum Berry
234 ATK/240 HP/16 SDEF/20 SPE
Bullet Punch
Dynamic Punch
Ice Punch
Payback
We ALL hate Machamp by now. He stops almost any lead. Although, ColburZelf is annoying, I can take it on with switching. Machamp also hurts stall pretty badly. Gyarados is the only thing that can handle it beacause bulk and resistence + recovery. Ice Punch handles Rose, although it's not that big of a threat. Theres also the factor that Machamp is like LeadQuaza. In most cases, you either set up SR, or die. Machamp hangs around most of the game so I always have a backup TTar check. Great Anti Lead, although Lucario and Gallade seem interesting.

Swampert
Adamant @ Choice Band
240 ATK/ 168 HP/100 DEF
Waterfall
Earthquake
Ice Punch
Stone Edge
Those weak Dragon Claw Leftovers Dragonite can't exactly hurt this guy even after DD beacause they lack enough power. Swampert smashes through hyper offence beacause he has alot of bulk to withstand hits. Also that most offencive teams nowadays lack a strong water resist. 100 Base Power STAB EQ isn't something to scoff at either. A few things that I always think off is using Standard Mix-Pert just to keep reagular ScarfTran and get rid of SR. Although, Swampert is a key member. He softens up stuff pretty easy with SR support. With Torrent activated Waterfall becomes incredibly powerful.

Heatran
Timid @ Choice Scarf
252 SATK/252 SPE/4 HP
Fire Blast
Earth Power
Explosion
Stealth Rock
My Ape check. Also does well with Machamp thanks to Lead Synergy. The fact that Heatran fools people into thinking it's ShucaTran gives it an edge when revenge killing Ape and SD Luke along with other threats. When I don't need Heatran, bombs away. Taking somebody down with me most of the time. Heatran is also a good Rotom counter, although a more defencive set would be better. Heatran always has an edge as he fools his opponent with SR. I got this idea from vashta's RMT. It really is a good set.

Rotom-H
Timid @ Choice Scarf
252 HP/252 SPE/4 SATK
Thunderbolt
Shadow Ball
Hidden Power[Ice]/Overheat
Trick
Trick screws up stall while HP Ice can take on Dragonite thanks to SR. This is also an emergency Ape check beacause Thunderbolt does a decent amount. Having 3 choicers is sordy iffy, but Reverb says it's ok thanks to Explosion and Trick. I had an issue with Starmie so Rotom came to mind. Although, Zapdos is a possible replacement as it can take on Starmie thanks to it's good SDEF. Although, SR screws it up. I also considered changing this set but I was never to sure. This is where you guys come in. Overheat is a possible move as it can check Luke, but Thunderbolt does pretty good.

Jirachi
Modest @ Expert Belt
114 HP/180 SPED/216 SATK
Calm Mind
Hidden Power[Ground]
Grass Knot
Psychic
This set is designed to lure in and KO opposing Heatran and Swampert which hurt Rotom and Heatran. It always KOs standard RestTalk Heatran with HP Ground. It runs 281 SPE so it can outrun Lucario and max speed Heatran. This set was made by reachzero but I customized to EVS to be more bulky and still have good power. Psychic has STAB and can hurt random things like Machamp and Breloom. Jirachi is a very valuable member as it has good synergy with the rest of the core. Jirachi is an amazing and diverse Pokemon. Theres not doubt it didn't find it's way on this team.

Dragonite
Mild @ Life Orb
112 ATK/200 SPE/196 SATK
Draco Meteor
Fire Blast
Superpower
Roost
Dragonite is used as my best Stall Breaker. It tears up stall into peices. With good attacking power combined with good synergy, Dragonite dosen't get beat easy. It's also used to kill Celebi thats walls Jirachi and Swampert. Draco Meteor is the best move in the game. It smashes EVERYTHING. Only one type resists it. Jirachi helps with this in killing Heatran. Something thats pretty annoying. Salamence used to go here, but hes Uber now. The fact that Dragonite can accomplish better stall breaking is very good. Superpower is a very nice addition. Roost also gives me reliable healing. Something New Mix-Mence wasen't able to do. Intimidate would be nice, but Dragonites still good as it is.

This concludes the team, I'm probubly gonna have to change a pretty large amount of this, but i'll do whatevers possible to make it better.

Rating by request.

This seems like a good start for a team, but there are definitely some changes I would like to see you use. First of all, I have personally never been a huge fan of Scarf Heatran + Scarf Rotom-A, and yet it seems to be a pretty popular combo these days. Both Pokemon pretty much check the same variety of threats. I'm also not a fan of Choice item Pokemon using Stealth Rock, because giving your opponent a free chance to set up is not always the best thing to do. Because of that, I would recommend changing your Heatran to a Shuca Berry Heatran, with the same moves. This should help you in safely setting up Stealth Rock while also remaining a check to Shaymin, who is one of the only threats Scarf Rotom-A can't check which Scarf Heatran can. I also want to recommend that you use max special attack on your Scarf Rotom-A, so that you can actually stop things that are at high health still. I usually love bulky Scarf Rotom-A, but your team isn't focused around entry hazards, so the ability to guarantee an anti-spin against Starmie isn't as necessary. Speaking of Starmie, you have to be very careful about letting it get in with this team, as it will likely take out a Pokemon if it does. In face, due to your large Starmie weakness, I would like to suggest that you change Swampert to Choice Specs Vaporeon instead. This will allow you to have a Starmie check while still boasting powerful hits that Swampert can. Also, Specs Vaporeon and Heatran tend to have similar counters, so I think you will find it neat that Heatran's Explosion will often allow you to open up the field for Vaporeon to really do damage. Next, I feel like your Jirachi set is trying to do too many things at once. You don't need Expert Belt to KO the Pokemon you're aiming at with Grass Knot and HP Ground, so I think you're better off going one of two routes:

The first route, which is my recommended route, is to use your same moves, but with Shuca Berry, and max Spe and SpA. This will allow you to bait out things like Flygon and weaken them with Psychic. With a weakened Flygon on your opponent's team, I think it would be neat for you to change your Dragonite to this set:

Dragonite @ Life Orb
Adamant, 252 Atk, 252 Spe, 4 HP
Inner Focus
-Dragon Dance
-Outrage
-Fire Punch / Earthquake
-Extremespeed

Combined with Shuca Jirachi, this thing will sweep a lot of teams, since everybody seems to rely on Scarf Flygon to beat both threats. The setup is, you weaken Flygon while it tries to Earthquake you, then go to Dragonite to get a free Dragon Dance. Then when Flygon tries to come in later, you can Extremespeed it to KO it, since it is weakened from Jirachi. This set would also provide you with a priority attack for general revenge killing purposes.

The second route you could take (which is inferior IMO) is to simply change your Jirachi to the standard Expert Belt set, with Fire Punch, Iron Head, Thunderbolt, and Ice Punch. With that you will have a good check against threats like Swords Dance Lucario, and you can also keep bluffing a Choice item and take opponents by surprise. If you go this route, I would say stick to your current Mix Dragonite instead of Dragon Dance.

Anyways, I hope you found my rate useful. Good luck in the future!
