I recently obtained a Back to Basics and I wonder what is a good ratio of Basic/non-basic lands so it doesn't hurt me more than my opponents.
I suppose that near to 0 non-basics is a trivial answer for a mono-color deck, but I want to add it to my blue/white Commander deck. I tried to cut the less essential utility lands, but I am hesitant to take out the "dual lands" because it would increase the inconsistency of my deck.
