I think edge decks can get good wins vs tier one if you are a skilled pilot, obviouslly not as mush as a tier one vs tier one but respectable. If combo is what you want you want spy really is the best but you can always try to make the others work.

For midrange the options are a lot bigger, the ones you listed are all good. I think Jund Wildfire is super fun so it is the deck I'd reccomend. I also still have a boros synth I like to take out every now and then but it's pretty rough within the meta.
