well I think this will be the final configuration for this deck. As always any comments or suggestions are welcomed.
Thought Scour draw is the most important thing about mill in my opinion it lets you get to what you need. also some small counters might be nice but Dispel is a side board alternative to Negate or Syncopate , reasons Pillar of Flame / Mizzium Mortars / Dreadbore . i was thinking going B/W because of Azorius Charm +Curse of the Bloody Tome with lock downs like Sphere of Safety and Martial Law and it could curve into Archon of the Triumvirate + Trepanation Blade
