Alright...
So, so far(I'm trying to make a team that can somewhat do good online) this is what I'm thinking for a team:

Impish Gliscore(Hyper Cutter or Sand Viel: Protect/Ice Fang/Toxic/Earthquake)
Jolly/Naive Cloyster(Shell Armor: Ice Shard/Icicle Spear/Surf?/Shell Smash)

Things I want to use in this team, though I don't know if they'd do good:
Virizion
Haxorus
Cofagrigus
Metagross
Bisharp
Volcarona
Kabutops
Delibird
Claydol
Jellicent
Bibarel
Lunatone/Solrock
Garbador
Cinccino
Krookodile
Lucario
Galvantula
Darmanitan
Klinklang
Crustle
Crobat/Swoobat
Scolipede
Whimsicott

Also, I seem to have forgotten how to do EVs!
Explanation would be nice, along with how to do it in Pokemon Black/White.

So, help me please?
