I've build a RDW that has been very successful for me 7-2 so far FNM record. The two things that I'm not sure about are the 2 mugging and the legion loyalists. I'm not sure of any other one drop other than Stromkirk Noble which I used and found too slow for my tastes. I'd be glad to hear any ideas, rants, or other hate for this deck. I'll take ideas on the sideboard as well but i've tried to cover all of the stuff that i've seen at my LGS.

Hellrider? It'd be the top of your curve but will almost guarantee the victory most times. Even as a 2x you'll end up getting several wins off of them.

Alternately, Foundry Street Denizen is a great option at the one-drop, as everything you're dropping is red, so he'll almost always be attacking with a power of 2 or more.
