Rate my Pokemon Black 2 Ingame Team! This is the team I used throughout the storyline. Tell me if it is good and if I should use it on my next playthrough in English. I did read the rules, and I only needed what I have put.
Samurott

Adamant Nature
- Swords Dance
- Waterfall
-
X-Scissor
- Return
X-Scissor > Megahorn for the increased accuracy.
Liepard

Timid Nature
- Nasty Plot
-
Dark Pulse
-
Hyper Voice
- Grass Knot
Dark Pulse is a tutor move in BW2, so go with that > Snarl as Dark Pulse is superior in terms of power and accuracy. Encore isn't that useful in-game; go with Hyper Voice for some neutral coverage.
Leavanny

Jolly Nature
-
Return
-
Swords Dance
- X-Scissor
- Leaf Blade
Leavanny is a bit on the frail side to be setting up Screens imo. Go with Swords Dance for boosting, and Return for a high-powered neutral coverage move.
Unfezant

Jolly Nature
- Hypnosis
/Toxic
- Fly
-
Return
- Roost
Hypnosis isn't that great for Unfezant. Toxic works better, especially alongside Fly as the Poison damage will really add up. Once again, Return for neutral coverage.
Lucario

Jolly Nature
- Close Combat
-
Shadow Claw
- Swords Dance
- Stone Edge
/ Ice Punch
Shadow Claw > Crunch. Fighting + Ghost is completely unresisted, whereas Fighting + Dark is resisted by two Pokemon iirc. Ice Punch is an option over Stone Edge for those Ground-types.
Ampharos

Modest Nature
- Thunderbolt
- Thunder Wave
-
Focus Blast / Signal Beam
-
Power Gem
Ehhhh RestTalking doesn't really work that well when you've only got Thunderbolt and Thunderwave as your other two moves. Go with Focus Blast or Signal Beam and Power Gem for some more coverage.
