Um, unless I've missed something, there is an inconsistency in the presentation of the game state.
After Flash resolves Ponder, Carrion Feeder is the second card from the top of the library. Vampiric is drawn from the top. Then Brainstorm is cast, without any shuffle effects in between, and the top 3 cards are:
Merchant Scroll
Mox Sapphire
Brainstorm
Where did the Carrion feeder go?
