Ideally this deck is an outlast deck. Slowly eating away at your opponent's health in the form of -1/-1 counters. I haven't played with it yet but I have two concerns. To start, I might have not put enough land in there (or too much) for all three colors. Secondly, I have a feeling that the creatures might not do enough damage to defeat the other player before you yourself get defeated. If that's the case I might get rid of red in favor of some white heals.
