As you maybe could of told by the title, this team is based around getting a successful sweep from a WishCM Jirachi. I have had mix reactions with this team, obviously some good, and some bad. I've come and posted my team in a hope that I could make it better with your rates and corrections.
Team Building Process

Obviously the center point of the team, The Star of David, a WishCM Jirachi.


I was looking at possible counters for Jirachi, Blissey ( it can become a problem, but it can also be dealt with ), Celebi and Swampert came to mind at first. Instead of finding counters to these pokes, I decided just to run a poke with Toxic Spikes. Considering aswell I didn't have a lead at the time, it only seemed right that I decided to use Roserade as my Toxic Spiker.



As I had Jirachi and Roserade there, it came to my attention that Heatran would obviously be able to cause problems. I also felt I needed a user of Stealth Rock, aswell as a possible user of Roar, so Swampert seemed to fit all those catergories




At this point I was considering a partner for Jirachi in terms of sweeping, considering I had most of the other things covered for Jirachi. I decided to go with Bulky Gyarados, as it resists Fire and Ground for Jirachi, and it can also setup on both Swampert and Heatran. In turn, Jirachi can setup on counters of Gyarados, such as Vaporeon and Celebi.





I decided I would need a revenge killer in case any situations got a bit messy, such as with a DD Gyarados or a DD Salamence. I also wanted something preferably not weak to Pursuit. I decided to go with a personal favourite of mine, Zapdos, as it is fast enough to kill both of them with a Scarf, but also resists the majority of Scizor's attacks, which is a bonus.






For my final member, I thought I would need something with could pack a punch, and lure certain threats out. I decided to go with Scizor, as with U-turn, has the ability to lure out threats such as Heatran and Magnezone, which I can deal with early in the game with accordingly.
So thats the team, at one more glance:






The members:

Roserade @ Focus Sash
Ability: Natural Cure
Timid; 252 Sp.Atk/ 252 Spe/ 6 HP
Moves:
- Grass Knot
- Hidden Power [ICE]
- Sleep Powder
- Toxic Spikes
Roserade is a great lead, being able to setup its Toxic Spikes on the majority of today's metagame leads. Focus Sash allows me to get at the very least 1 layer of Toxic-Spikes up. Grass Knot is for STAB, and allows me to deal with leads such as Hippowdon and Swampert. HP Ice allows me to maintain max Speed, thus putting to sleep any other Roserades that may run HP Fire instead. It also allows me to deal with Gliscor leads, and any Salamence that switch in attempting to setup. Generally with most slow leads that don't get hit super-effectively by Grass Knot or HP Ice, I sleep and begin to setup Toxic Spikes. As stated beforehand in the Team Building, Toxic Spikes allows Jirachi to take on the likes of Blissey, Swampert and Celebi 1v1 and come out on top.

Swampert @ Leftovers
Ability: Torrent
Relaxed; 252 HP/ 252 Def/ 6 Atk
Moves:
- Earthquake
- Ice Beam
- Roar
- Stealth Rock
Ah Swampert, my "second" lead in a way. Generally when Roserade goes down, I bring this thing in to either setup Stealth Rocks, or scout his team via Roar. Swampert is an important member of the team, allowing me to defeat Heatran, Salamence, Tyranitar and also allowing me to lure in Celebi. Earthquake and Ice Beam form great type coverage, but also allow me to deal with some of the threats I had named above. He also resists Jirachi's Fire and Ground weaknesses, which provides defensive stability in order to help Jirachi.

Gyarados @ Leftovers
Ability: Intimidate
Adamant; 156 HP/ 96 Atk/ 72 Def/ 184 Spe
Moves:
- Dragon Dance
- Return
- Taunt
- Waterfall
Gyarados, the best that once terrorized the olden days of Blue and Red verison is still around to haunt those of the new metagames. Gyarados is the perfect offensive partner for Jirachi, as it covers both it's Fire and Ground weakness, it has access to Taunt, which can possibly give Jirachi a free switch-in from any status moves like Will-o-wisp or Thunder Wave. It can setup up on both Swampert and Heatran, while Jirachi can setup on both Celebi and Vaporeon. Gyarados also allows me to tackle Scizor and Lucario, who can pose a problem to Jirachi if it is not outsped, or if Jirachi hasn't CMed yet and Scizor is specially bulky. Gyarados can also switch in on CB Tyranitar that isn't locked into Stone Edge, and proceed to prove problems. Dragon Dance is fairly straight forward, allows me to up my Attack and Speed in one move. Taunt protects Gyarados from being phazed out and also statused. Waterfall and Return provide excellent coverage in OU, as it's only resisted by Empoleon and the rare Shedinja. Also, I was wondering about the EVs, do I really need that much Speed invested? If anyone has some suggestions on that, I'm all ears.

Zapdos @ Choice Scarf
Ability: Pressure
Timid; 80 HP/ 252 Sp. Atk/ 176 Spe
Moves:
- Heat Wave
- Hidden Power [ICE]
- Thunderbolt
- U-turn
Zapdos has proved to be a very good revenge killer for so long as I have been using it to do so. It can easily save my team from the likes of a DD Gyarados, DD Salamence.With Fire, Ice and Electric, no pokemon resists this type combo except for Lanturn, which is fairly uncommon in the realm of OU. With Heat Wave, Zapdos has a reliable way of revenge killing Scizor, Magnezone, Lucario, and Metagross. Speed is not used on Zapdos often, so I often treat it as an element of surprise, which will certainly help me with with this set.

Scizor @ Choice Band
Ability: Technician
Adamant; 162 HP/ 176 Atk/ 168 Sp.Def/ 4 Spe
Moves:
- Bullet Punch
- Pursuit
- Superpower
- U-turn
CB Scizor is quite the handful and quite the threat, with its ever popular priority move Bullet Punch, Scizor likes to cause problems. Scizor allows me to lure in Heatran and Magnezone incase my opponent has them, and attempt to deal with it accordingly. It also allows me to kill Salamence if any of my other team-members who deal with him are down, and it also helps me kill Tyranitar, Latias and Blissey. I never liked Scizor all that much due to his overusage and depedency on Bullet Punch and U-turn, however, I don't see what else I could put in here or do with it.

Jirachi @ Leftovers
Ability: Serene Grace
Bold; 252 HP/ 220 Def/ 36 Spe
Moves:
- Calm Mind
- Flash Cannon
- Thunderbolt
- Wish
Be it fitting that I give the title to this RMT as Star of David not only due to the time of the year, but also due to my little friend here. Jirachi is a monster of a sweeper, being able to run through ( I say run through, but it doesn't have that much speed, but it's an expression!!111 ) teams that are unable to deal with it. This set provides me with much needed physical bulk in order to setup on alot more pokes then I could before ( with 176 Spe, to outspeed Luke ). Flash Cannon and Thunderbolt are very good together as they have excellent neutral coverage. Wish is there for me to heal so I can be around for a long time, and I can also pass Wishes to any of my teammates if needs be. Normally, Jirachi has an easier time setting up when it is switched into a resisted attack, such as Scizor's Bullet Punch. However, due to the bulk on both sides of the spectrum this guy can have if I've started to Calm Mind, I feel that anything without a status, phazing or Super-effective move can make for a perfect candidate.
Well there you go, that's my team, I hope you enjoyed reading it and maybe reply shortly for some assistance to me and the team.
Regards.
