Thanks for the article, it was a good read. Some little nitpicks:

Street Wraith - drawback of being vanila 3/4 creature is not that bad when playing against fish. Also,
My gut says that there is diminishing utility per Street Wraith whenever you add a Street Wraith, but this could be incorrect for various reasons.
this looks like 60 vs 61 cards in a deck argue. And we all know how that ends usually.
Aven Mindcensor - casting cost of 3 could prove to be a serious drawback, especially in fish where creatures usually cost 1 or 2 mana.
Sumonner's Pact - it can grab Protean Hulk, which means instant win in combination with Flash. Then again, Smmenen says it's bloody awful.
