@nedleeds I've considered running 1 in the past and may still do so but I don't think you could run more than 1 anyway because it doesn't stack and isn't blue. So, at most I'd do a 1/2 split of sylvan and chart. I really have come to like the burst that chart provides, though. I also really like that I'm not nuking my life-total to do so.
Search for Azcanta could replace Sylvan Library/Chart a Course, is blue, and synergizes really well with Knight of the Reliquary or Ramunap if you decided to add either. Also binning that useless Daze or 2nd Thalia instead of drawing dead cards seems very good in a list like this.
@topical_island I cut it back in 2010/2011 when I played this deck a lot it was very good back then. It really helped in the mirror since this deck was fairly heavily played at that time. I think now you would just lose to PO if you cut the FOW.
