I recommended a Voracious Wurm, and a Faithmender if it fits your budget.

This deck has WAY too few land i tested it against a treefolk and a curse deck and i kept getting mana screwed. Hell, i added 30 Black Lotus and i still didnt stand a chance.
Why? Is storm crow banned because its so over powered?
I love the use of flying in this deck, too bad you cant have more storm crows.
