Red feels like the weakest color to me based on commons and uncommons but still has strong enough rares and should pair fairly well with green among the other colors.

My gut instinct tells me that Green is once again the strongest color, and while I think Green/Red will be an undervalued pair, all Green/X pairs look solid to me, and I am particularly excited for Green/Blue..

I can't decide if White feels weak or not outside of Auras strategies.

Tri-colors shouldn't be an issue in this format. If anything, Quad-colors shouldn't be a problem for some color sets if you include Colorless, such as UGBV or UGRV or even UWBV.
