The Team
Medicham @ Choice Scarf
Adamant
252 Att/252 Spe/6 HP
Ice Punch
Thunder Punch
Hi Jump Kick
Psycho Cut
I love this guy. He always pulls me out of situations I can't handle (revenge killing non-Scarfed Garchomps, taking out Blissey, beating Heracross, etc...) He makes a pretty good lead (albeit walled by Bronzong and other seriously bulky leads)
Gliscor @ Leftovers
Impish
252 HP/252 Def/6 Att
Earthquake
Taunt/Stealth Rock
Roost
Physical wall and fighting resist. Eats apart Hera and Lucario (able to beat the other easily with EQ) Ice Fang for my Garchomp problem, whereas EQ handles other problems I face such as Metagross, Tyranitar, etc...Taunt is awesome and could help me with CroCune, but Stealth Rock is an awesome thing to have lingering on the opponents side.
Blissey @ Leftovers
Calm
42 HP/252 Def/216 SpD
Aromatherapy
Seismic Toss
Softboiled
Toxic
Toxic helps me in long stall wars in the end of the match, since it will allow Bliss to gain extra damage (Seismic Toss and Toxic add up VERY quickly) I use Aromatherapy because my team gets hurt quite a bit by status (also considering only Blissey has a reliable instant recovery, Pain Split can't do the job sometimes)
Gyarados @ Life Orb
Adamant
72 HP/252 Att/186 Spe
Stone Edge
Waterfall
Ice Fang
Dragon Dance
LO Gyara is great for late game, although it can still leave a dent in things that would usually counter it. The first slot is a toss up. Waterfall makes an incredible STAB. Ice Fang and Stone Edge provide amazing coverage, hitting Gyarados AND dragons.
Metagross @ Choice Band
Adamant
244 HP/252 Att/14 Def
Meteor Mash
Earthquake
Ice Punch
Bullet Punch
CBGross is a great switch in to weak physical attacks, and it makes a very nice Deoxys-e killer with Bullet Punch. BP 2HKO's standard TTars and such. Meteor Mash gives me a nice option to sweep teams in late game. EQ is standard. Ice Punch is for bulky dragons who aren't going to be 2HKO'd by the Mash.
Vaporeon @Leftovers
Bold
188 HP/252 Def/70 SpD
Wish
Surf
Protect
HP Electric
Mixape, and Gyarados counter. Comes in on predicted Surfs, Wishes up, and heals my team. Works nicely with Bliss because I can literally fully heal my team with removing status and recovering their HP.
