B/R Rakdos Deck

... okay... going to have to give us more than a list to work with here.  Is this for casual play or a more competitive setting?  Are you wanting to take it to FNM or do you envision Grand Prix success in your future with it?  Are you looking to keep it within a specific format or are you open to whatever?  Do you have an idea of how much you're willing to spend to improve the deck?  What does your local meta-game look like?  What sorts of decks do you typically play against?  Are there match-ups you envision yourself having trouble with?  What is your primary win-con?  If you were to come up with an ideal starting hand and 5-6 turns, how would they play out?

As I've said probably a hundred times on this forum by now, the more information you give us, the more likely it is that we can give some meaningful comments.  Simply posting a decklist is likely going to just have your post largely ignored.
