I'm ready to take on the elite four and champion of Sinnoh in pokemon platinum, what moves should I teach all 6 of my pokemon?

My team consists of Torterra, Gastrodon, Gliscor, Wormadam (ground type), Garchomp and Mamoswine.

I can have any move I want as I've explored everywhere possible before the elite four and I have a Starly that learns fly so its easy for me to fly town to city without having to use HMs on any of my main six and I plan on having all the HMs that I do have on my team deleted so they can have a full set of amazing moves for battling.
