So am I correct in assuming that this is for an FNM? Or is this for casual play?
The biggest issue I'm seeing is that your deck will have very little consistency. Typically the reason that people run higher counts of cards, 3-4x, is because those cards are central to the deck and they really want to draw them frequently.
If you're interested, here's an R/G midrange build I've been tinkering with, feel free to take or leave any of the structure behind it: http://deckbox.org/sets/474989" onclick="Tcg.mtgCard.showNewCard('http://deckbox.org/sets/474989');return false">http://deckbox.org/sets/474989
I can happily explain any of my card choices or go through the specifics of your deck more later once I know the type of competitive setting you intend to play in with this.
