Rate my team. Jirachi l.v 100 moves: draco meteor(learned by a special..

I give this a 6/10. Half your team is weak to Ground, and you have two Poke's with a double weakness to Ice. The movesets could also use some work. For example, your Jirachi is using almost all special moves, and is carrying Draco Meteor. The problem with this is that after just one or two Draco Meteors, you won't be able to hit anything very hard. You could put Calm Mind on him to try and negate this effect, or you could give him a mixed set. This is what I recommend.

Jirachi:

Nature: Bold
Ability: Serene Grace
Item: Leftovers
EV's: 252 HP, 224 Def, 32 Spd.
Moves:

Wish
Calm Mind
Thunderbolt
Flash Cannon/Psychic

Jirachi has a great defensive typing, and he makes the most of it here. With this set, you can set up with Calm Mind, using Wish as necessary, then hit hard with T-Bolt and your other move. When choosing between Flash Cannon and Psychic, think about some of the common offensive and defensive threats. Flash Cannon can hit opposing T-Tars, the Latis, and Celebi harder than Psychic can. However, Psychic can hit most things that resist Flash Cannon. An added bonus on this Jirachi is that you can send him in, use Wish, then switch out to another Poke so that he gets the healing effect.

I'm going to be brutally honest here, your Gengar is an abomination. It focuses far too much on putting your opponent to sleep, and Night Shade is an ineffective attack for him. A Banette with Insomnia could royally screw this guy over. I would change him quite a bit.

Gengar:

Nature: Timid
Ability: Levitate
Item: Life Orb/Choice Specs
EV's: 252 Sp. Atk, 252 Spd.
Moves:

Shadow Ball
Thunderbolt
Focus Blast
Energy Ball/Psychic

This is an all out offensive Gengar, and he hurts. Shadow Ball is a great STAB move, and will almost always do more damage than Night Shade. Thunderbolt gives you some good coverage, and allows you to hit Pokemon like Skarmory. Focus Blast allows you to hit any Normal types that come into play. Energy Ball also gives you some nice coverage, allowing you to hit Swampert and Quagsire hard. You could swap it for Psychic to hit any Fighting types that come in, but Shadow Ball can hit them as well, and gets a STAB boost, making Energy Ball preferable.

Tyranitar's presence on the team worries me. Only one of your Pokemon is immune to the sandstorm damage, and the team is not built to function well in it. If you really want a Rock type on your team, this is what I would recommend.

Rampardos:

Nature: Jolly
Ability: Mold Breaker
Item: Choice Scarf
EV's: 252 Atk, 252 Spd.
Moves:

Head Smash/Stone Edge
Outrage
Superpower
Earthquake

Sitting at a healthy 354 Speed, and a massive 429 Attack, this guy will punch holes in the other team. He has access to Head Smash, but due to the massive recoil, I prefer Stone Edge. Both are very powerful STAB moves, and they both have 80 accuracy. Earthquake is another great move on this set, as it should allow you to OHKO Sheer Force Nidoking if he comes against you. Outrage lets you hit Dragon types like Garchomp and Haxorus. Superpower lets you hit Darkrai hard, and can hit Steel types floating on Balloons.

Your Salamence could also use some work. Zen Headbutt doesn't help him at all, and Fly is an absolutely useless move. Here's my recommendation.

Salamence:

Nature: Rash
Ability: Intimidate
Item: Life Orb
EV's: 220 Atk, 112 Sp. Atk, 176 Spd.
Moves:

Dragon Dance
Dragon Claw
Fire Blast
Roost/Earthquake/Brick Break

Salamence has a lot of potential, and this set helps use it. After a single D-Dance, Salamence becomes one of the most threatening offensive Pokemon in the game. With Dragon Claw as your primary attack, you can deal large amounts of damage without being locked into a move. Fire Blast takes out Ferrothorn, who resists Dragon Claw, and also hits Excadrill hard. However, Salamence is weak to Stealth Rocks, and holds a Life Orb, and that can stack up. Roost can hold the solution to this problem. Not only does it heal him by 50% of his max HP, it takes away his Flying typing for that turn. However, he is also threatened by Pokemon like Heatran, who resists Dragon Claw and absorbs Fire Blast. You can choose Earthquake over Roost in order to hit Heatran with a 4x super-effective Earthquake, or you could run Brick Break to counter Blissey, as well as Empoleon.

Raichu is just a bad choice all around. He doesn't have great stats, and while his movepool may seem decent, most moves are wasted on him. I would recommend Raikou over him.

Raikou:

Nature: Rash
Ability: Pressure/Volt Absorb
Item: Life Orb/Leftovers
EV's: 252 Sp. Atk, 176 Spd, 80 Sp. Def, or 252 Sp. Atk, 252 Spd, 4 HP.
Moves:

Aura Sphere
Thunderbolt
Calm Mind
Hidden Power Ice

Rash Raikou gains access to Aura Sphere, something this set takes advantage of. With Calm Mind boosting not only his offensive power, but his defensive power as well, Raikou is a formidable opponent. With an excellent STAB move in Thunderbolt he is able to take out a variety of foes, including an un-Sashed Cloyster. Aura Sphere is a powerful move, and it will never miss, so you can always rely on it. HP Ice finishes the set by allowing you to hit the Ground types that are immune to Electric, and the Grass types that resist it.

Garchomp isn't too bad, but Crunch and Fire Blast are both useless. I would honestly prefer Flygon, but that's your choice.

Garchomp:

Nature: Adamant/Jolly
Ability: Sand Veil
Item: Focus Sash/Life Orb
EV's: 252 Atk, 252 Spd.
Moves:

Outrage/Dragon Claw
Earthquake
Swords Dance
Brick Break

This guy will hit hard. A Focus Sash will guarantee you get a Swords Dance off, provided there are no entry hazards up, but Garchomp also has a weakness to Ice Shard, and has no priority of his own. What he does have though, is a lot of power. After a single Swords Dance, his Attack will be upwards of 600, even with a Jolly Nature. With said Nature, his Speed is also at 333, which is nice to have. The choice between Outrage and Dragon Claw is yours, but remember that after a Swords Dance, it will hurt quite a bit if you hurt yourself. Dragon Claw is safer, and doesn't lock you into a move, but it's also weaker. Earthquake provides you with a powerful STAB move, and hits the Steel types that resist your other STAB. Brick Break finishes the set off, allowing you to hit Blissey and Chansey, as well as Ferrothorn and any other Steel types that might be floating on a Balloon.

Well, that's all. I hope this helps you in some way, shape, or form.

Your team is great! I would rate it 10/10! Great job!

Hope this helps!

It looks good so far. But to be able to properly rate it, you must list move sets.

If the team is legitimate, then I would rate it up to 9/10 (if the movesets are good). The problem is you have two dragon types, each sporting a double weakness to ice.

If the team has been hacked to any degree, then no more than 4/10.
