I made a first draft of a Megatron commander deck and looking for feedback and tips on what to add/cut

I recently got into EDH and wanted to make a deck with the transformers cards. My main goal is to make a budget deck and so I would like to keep individual cards under $15\\\~ (aside from the commander) and I would like to keep all of the transformers cards in the deck. This is my first time building and EDH deck so please give me any feedback
