There's a girl passing by. No, I think that's a guy.

[.Vaati.]

Weavile @ Expert Belt
Trait: Pressure
EVs: 6 HP/ 252 Atk/ 252 Spd
Nature: Jolly
- Ice Punch
- Pursuit
- Brick Break
- Aerial Ace

I usually use Weavile for my starter and it works pretty well. I was considering Life Orb but that with Stealth Rock and Sandstorm it may hurt more than help.

Heracross @ Choice Scarf
Trait: Guts
EVs: 6 HP/ 252 Atk/ 252 Spd
Nature: Adamant
- Close Combat
- Megahorn
- Stone Edge
- Sleep Talk?

Heracross is the main physical sweeper. I used to have Pursuit for the last slot but I heard that it was just a glitch in the Japanese version. I used Sleep Talk since I don't have an Aromatherapist or a Sleep Absorber.

Swampert @ Leftovers
Trait: Torrent
EVs: 252 HP/ 108 Atk/ 150 Def
Nature: Relaxed
- Earthquake
- Hammer Arm
- Ice Beam
- Stealth Rock

Hammer Arm is mainly for Tyranitars and Blisseys. I would use Avalanche but Ice Beam allows Swampert to counter both Blissey and Skarmory. I think the EV spread may need more work.

Jirachi @ Leftovers
Trait: Serene Grace
EVs: 240 HP / 56 Atk / 76 Def / 136 Spd
Nature: Careful
- Reflect
- Wish
- U-Turn
- Zen Headbutt

Provides much needed Wish support since Swampert gets worn out quickly. I got a Bold one but the IVs aren't that great. I'll rework the EVs once I figure out my Jirachi's IVs.

Cresselia @ Leftovers
Trait: Levitate
252 HP / 48 Def / 136 SAtk / 72 SpDef
Nature: Sassy
- Ice Beam
- Grass Knot
- Moonlight
- Reflect

Helps counter Dragons, something I was having a huge problem with because I got her. I have a Bold one but the IVs aren't that great compared to this one, which has 20+ in every stat.

Salamence @ Choice Specs
Trait: Intimidate
6 HP / 252 SpAtk / 252 Spd
Nature: Modest
- Draco Meteor
- Hydro Pump
- Fire Blast
- Dragon Pulse

The main reason I chose Salamence was because I thought I needed something with Intimidate and could hit hard with Special Attacks. I may try a mix set but I'm not sure at the moment.

There may be a few flaws. I think I did most of it correctly though.

Salamence - Cresselia, Swampert can stop attack oriented ones
Tyranitar - Swampert
Metagross - Swampert, Salamence
Dragonite - Swampert, Cresselia
Heracross - Weavile, if it's lucky - I need help covering up this weakness, Reflect on Jirachi and Cresselia can help slow it down
Zapdos - Swampert if it doesn't have Hidden Power Grass, Cresselia
Gyarados - Not sure x-x;
Garchomp - Cresselia, Swampert can if a Reflect is up
Starmie - Cresselia, Jirachi?
Alakazam - Weavile
Gengar - Weavile
Weavile - Swampert
Dugtrio - Swampert, Cresselia
Manaphy - Cresselia?
Celebi - Cresselia, Weavile, Salamence?
Blissey - Weavile, Heracross, Swampert
Gliscor - Swampert
Rhyperior - Cresselia, Swampert, Heracross
Jirachi - Heracross, Swampert, Weavile?
Electivire - Swampert, Cresselia may
Hippowdon - Swampert, Cresselia
Suicune - Cresselia
Raikou - Swampert - if it doesn't have HP Grass, Cresselia - maybe?, Not sure
Snorlax - Heracross may able to
Skarmory - Swampert, Cresselia,
Azelf - Weavile
Mesprit - Weavile
Cresselia - Weavile
Heatran - Swampert
Lucario - Swampert
Infernape - Not sure. There are a lot of sets. ><;
Staraptor - Swampert, Cresselia,
Swampert - Cresselia
Milotic - Cresselia
Sceptile - Cresselia, Salamence?
Rampardos - Swampert, Cresselia, Salamence?

Your team seems to work well to me. Swampert seems like a better lead than Weavile since it's less fragile, but if it works for you then I won't talk what I don't know since I've never used a Weavile lead before.

I don't think Infernape is a particularly huge threat to your team even though it'll wreak havoc, but you're right that it's Gyara-weak, especially since there's not a single electric attack. Hera has Stone Edge but other than that, good luck.

I don't know if Sleep Talk is good for Heracross unless you're counting on a sleep condition, but you're right that you don't have a sleep absorber. I'd go with Night Slash/Shadow Claw if you don't want Pursuit (it gets at Dusknoir pretty well.) Speaking of Dusknoir, I don't see any "real" trouble for you handling it, but it won't exactly be easy to take down.

(I wrote way more than I thought I would.)
