As soon as I can get another Dark Fusion, I'm going to add another Dark Gaia. Other then that, I'm completely lost on where I should go from here. What are some good Rock and Fiend monsters with high attack? Also, any other suggestions on Magic/Trap cards?

Note: Some of the monsters don't seem very good in this deck, but these were the most powerful Fiends and Rock monsters I could find in my collection, and that was the most important objective of this deck, but I don't have any good Fiend/Rock effect monsters that help the deck much.
