Which Pokemon are most efficient at soloing Pokemon League rematches in Black 2 and White 2?

The fastest way to get the Challenge Medals in BW2 is to grind one or two Pokemon of a type and use them for the Elite 4 rematches. If one wanted to get all nineteen of these medals, which Pokemon would be the best to do so? Please list one to two per type, and mention in your answer:

For example, a recommendation of Excadrill would note that it’s one of the strongest Steel types in the game, allowing for easier completion of an otherwise difficult typing. This joined with a high Attack stat, STAB Earthquake, and dual typing makes it a premier choice for a challenge such as this.

Thanks in advance.

Here are what Ibelieveto be the best of each type

Normal: Braviary is chosen because of Marshals Fighting types.

Braviary Lvl. 80+Item: Choice Band/Muscle Band/LeftoversJolly NautreAbility: Doesn’t matter, Defiant if possible- Brave Bird/Fly- Return- Superpower- Shadow Claw

Braviary is unfortunately a White 2 Exlcusive however, so as a substitute here is an Unfezant set.

Unfezant Lvl. 90+Item: Choice Band/Muscle BandAdamant NatureAbility: Super Luck- Fly- Return- U-Turn- Roost/Steel Wing

Flying: Archeops is good, but don’t let it go under half its HP.

Archeops Lvl. 80+Item: Choice BandAdamant NatureAbility: Defeatist- Rock Slide- Fly- Crunch- U-Turn

Bug: Crustle has good typing for the E4.

Crustle Lvl. 80+Item: Choice BandAdamant NatureAbility: Shell Armor- X-Scissor- Shadow Claw- Earthquake- Aerial Ace

Rock: Archeops again.

Grass: Whimsicott has good move type diversity and speed.

Whimsicott Lvl. 80+Item: Choice Specs/LeftoversModest NatureAbility: Prankster/Infiltrator- Giga Drain- Psychic/Hurricane- Shadow Ball- Stun Spore/U-Turn/Leech Seed

Dark: Hydreigon, I left a set in the comments

Dragon: Hydreigon again.

Ghost: A tough region for the Ghost type, I think Chandelures, 140 Special Attack can get through.

Chandelure Lvl. 80Item: LeftoversModest/Bold NatureAbility: Flame Body- Flamethrower/Heat Wave- Shadow Ball- Psychic- Will O Wisp

Just power your way through Grimsley with Flamethrower.

Fire: Darmanitan is very powerful.

Darmanitan Lvl. 80+Item: Life Orb/Choice BandAdamant NatureAbility: Sheer Force- Fire Punch- Hammer Arm- Zen Headbutt- Earthquake/U-Turn

Ground: Excadrill has a nice dual typing that helps it resist dragon, psychic, dark and ghost! Just make sure to brute force your way through Marshal though with Earthquake.

Excadrill Lvl. 80+Item: Choice BandAdamant NatureAbility: Sand Force- Earthquake- Brick Break- Rock Slide- Shadow Claw

Steel: Excadrill again, though Lucario could probably solo well too.

Lucario Lvl. 80+Item: Choice SpecsModest NatureAbility: Inner Focus- Aura Sphere- Shadow Ball- Psychic- Dragon Pulse

Fighting: Lucario again.

Psychic: Metagross. I probably don’t need to explain why.

Metagross Lvl. 80+Item: Choice BandAdamant NatureAbility: Clear Body- Meteor Mash- Zen Headbutt- Brick Break- Earthquake

Water: Samurott due to its good type diversity, and high offensive stats.

Samurott Lvl. 80+Item: Choice Specs.Modest NatureAbility: Torrent- Scald- Ice Beam- Air Slash- Hidden Power Fighting/X-Scissor

Ice: Lapras has good typing and move diversity that makes it a good candidate for the best Ice type for the Unova E4

Lapras Lvl. 80+Item: Choice Specs/LeftoversModest NatureAbility: Shell Armor- Ice Beam- Psychic- Signal Beam- Thunderbolt

Electric: Not the best choices, but I think Galvantula can preform well.

Galvantula Lvl. 80+Item: Choice Specs.Modest NatureAbility: Compound Eyes- Thunder- Bug Buzz- Energy Ball- Discharge

Posion: There are no really good poison attackers before Gen 5, but Crobats solid.

Crobat Lvl. 80+Item: Choice SpecsModest NatureAbility: Inner Focus- Air Slash- Sludge Bomb- Shadow Ball- Heat Wave

Alright, that’s all of them, please tell me if you think these did well, or if there are any issues, moveset wise, or if there’s a better Pokémon.
