yay a dratini with extremespeed and a larvaitar

After Countless Searching in Soul Silver I unlocked a dratini with extreme speed and a larvaitar

And now for a helpful post that isn't bragging!Dratini with Extremespeed can be found in Dragon's Den by answering the Elder's questions correctly. Larvitar are found wild inside Mt Silver at L15 and L20.

So what's a good moveset for Dragonite that includes Extremespeed?
I figure it's not really needed because of Dragon Dance's presence, but who knows?
