EQ is no great addition to this deck. Your goal when using EQ is to deny your opponent his game. So, if you slow down your opponent's offense (or defense) with EQ, you want to rush him down asap before he can recover, not have some defensive low damage combo.
My opinion:
-The deck can use 2 or 3 Dragons as a finisher.
-The deck does not need Devourers, despite their strength. Gargoyle+LS costs too many cards to splash in six 0 (or 2) damage creatures.
