I just finished getting the moves for my Gallade.
Gallade:
Item held: Shell Bell OR Leftovers.
Moves:
Psycho Cut
Focus Punch
Substitute
Swords Dance
Don't even need to explain myself. Of course, it's a kind of a... "personal" strategy (Kind of hints you in on how I got this strategy

).
I'll see about getting back onto Wi-Fi, although I can't guarantee anything.
