A FG named basilisk needs basilisk blood and auburn nymph :p
And in regards to the shield, the primary use for it in this deck I'd think would be the reflection. (otherwise, diamond shield makes more sense) With all the wardens, there's some good creature control here, and the shield protects against some spells as well.
Being the jerk that I am, I'd recommend a Quicksand or two as well

Not as many as Seism, but just one or two, so the opponent is never sure whether one is coming or not. (against seism, you just assume he's got like 4 in opening hand :p with 1-2 in the deck, you'd have to gamble more)
