This sounds like the beginnings of an awesome Saheeli, the Sun's Brilliance Commander deck
Blue also opens up some interesting Auras
I have included some of the best Initiative cards in my cube (best is rather subjective, and there are a couple of others, that can be equally great), and every time I have now drafted it, at least one person in the pod is surprised about the stupid powerlevel of these creatures at some point throughout the evening
Im sure it wont make too much of an impact on Commander as it doesnt do anything when it hits the board, but those EDH players do love drawing cards, so itll probably hold at least some value
modal lands that bounce themselves or other cards so players can make use of the spell side once they have enough lands
I have to compliment the Wizards team for just how well they managed to bring the feel and personality from Fallout over into Magic
