I was actually aiming for a G/R deck I could rate a 5, as the only other one I had was Fast Friends (7-2). I forced myself to review every creature either or both could cast without requiring other colors of mana, and when I started paring things down, there was very little green left, so it got junked. The rest of the work required that I cut the creatures down and add some non-creature cards (along with some additional creatures since it was now back to red only). I dropped most of the tapping pokers and focused on battalion and boosts, plus a lot of pain from death. The result was a reasonably cheap deck at 2.28 average cost on a 15/12/6/3/2/2 curve.
