Waterfall/Aqua jet aqua tail-Priority moves rule LC, so I'd go with that.
Dragon Dance-boosts his sweeping stats, he could use some help in speed. swords dance is fine too, if the team is slow.
ice punch/mud slap-Covers grass weakness, mud slap can be annoying to electric types, the only problem is that it's special, but yet again, you don't use it for the damage, but for the accuracy being lowered. Ice punch helps you deal with dragons though.
Shadow claw/Crunch/iron tail etc-a good physical move to give him more coverage.
