Tentacruel- seems good. Mirror coat or sludge bomb maybe for the last slot
Espeon- nifty, go with bite (in game) or hp dark/fire I think.
Zangoose- nice stuff
Skarmory- an old standard but it's still good. rest + chesto is good, drill peck if you want.
Wobbuffet- encore over destiny bond and you've got yourself an evil moveset
I'm not sure what you could put in the last slot. Maybe heracross?
choice band with hp rock, earthquake, megahorn, brick break is the standard. I like reversal tho.
