you should be using 4 birds and 2 heirarchs. you probably dont even need the heirarchs in the deck tbh. its not like you are planning on attacking. getting black seems to be important. especially double black for echoes.
also, the explore should be one of the jaces. The tome scour should probably be some kind of removal. with only 2 fogs, the deck needs it. you also might want some more ponders in the deck just to draw what you need.
The people that play legacy / vintage always amuse me. They want their formats to be represented more. They want more tournaments. But when anyone suggests allowing more people access to the formats by reprinting cards, the same people start screaming about the reprint policy.
I don't quite understand the splash for green. the fog could be replaced with Angelsong and the Explore could be somewhat replaced with silence or time warp... am I missing something? (no I haven't had the chance to play arround with explore yet but I doubt it is worth splashing green for it.)
