you took out 2 SN but added only 1 Qtower, meanwhile adding 2 other cards of elements. this put even more stress on quanta -- and the advice for SN vs Qtower number was to provide constant quanta incase of lack of SN in draws
in a 30 card deck, how often will you get blessing or SoW AND dune scorp? rarely, you won't even believe how many times i have run firecell (34 cards) and gotten the 1 vulture as last draw. also, with a 6-7 ttw, dune+bless is actually slowing you down (this strategy is meant as damage built over time, not a big rush)
my opinion on re-edit: -1 bless, -1 dune, -1 SoW, +1 Qtower, +1 BH, +1 RT.
my opinion of why -1 SoW above and possibly why another -1 SoW: this change could warrant addition of creatures to the deck, which combats the chance of CC (1 more creature to make sure CC has less chance to ruin you vs 1 power up that doesnt prevent CC)
what would i add in place of this 2nd SoW? perhaps a psion or
spider, perhaps exchange crawler with mind flayer and add forest spirit, maybe another graboid, maybe a wyrm (with the FWs upped of course)...many options
