As expected, this deck is strong, very likely too strong. I will leave it in for the time being and see how often it comes up. I am concerned that mulling to Zuran Orb simply has no downside. With higher than normal land count, short of holding up Spell Pierce, no deck can be fast enough. The combo with Clear the Mind means the ZMC player only needs stack life up and wait for CtM. Add in a minimal amount of blockers to play too and I think the deck is more or less unstoppable.
Mike got a nice crack at it in the draft with ZO and CtM in the same row on his pick. Thinking about it further, you have to be able to counter both spells.
I'd like to keep Clear the Mind in to enable the mill/control deck but my feelings are that, in order to maintain any kind of tension for the control deck, Zuran Orb will have to go, it simply makes the deck too formidable in the very early game. Feldon's Cane might be a good option however I am also wary of adding anti-mill tech with no colour restriction.
Follow up questions for later thought... How likely is this to occur? Is it worth the occurence of it at all, even if it is very low likelihood? Will this warp the draft totally around the two cards?
I think the deck is too intuitive to draft and play and too stable from the outset. It feels that there is no tension in the gameplay, only inevitability.
