2/3* Intuition (in place of 1 top, and 1 F/I) might be a good idea, at least for G1. Post SB, I'd prefer to side them out because of Extirpate and Surgical Extraction.

However, I'm not a big fan of removing Time Stretch from the SB. Because Intuition on Conflux would prevent us from storming efficiently. And I would also be afraid of my opponent playing land + Innocent Blood with back-up or several in 2 turns.

What would be Meltdown for ? I recall that you play F/I to deal with Trinisphere or Canonist. I cannot think of another really annoying spell (except chalice@2, but you can't BW under it anyway...). Eye of Nowhere is pretty useless since it's a sorcery and I don't think you'll have a lot of opportunity to play Eye + DH in the same turn. If your plan is to Eye + SnT, then it basically does nothing... (except for Meddling Mage, but once more, F/I and Firespout are more effective to deal with it)
