Is this something you want to make for Modern? Also, have you considered that new RTR double strike 2-drop?

You are running too many equiptments, I would suggest that you either cut down to a total of 2-3 swords and 1 batterskull, and add Darksteel axe/bonesplinter/silver-inlade dagger for the speed of the deck, so that you can be swinging a bit earlier than T4 with an equiptment. Another card you could add would be flayer husk, since if you stick a puresteel it cycles fairly well.

Espeth, Ranger of eos, figure of destiny might also be good additions if you find the space for them, maybe even vial?

at the very least i would say you should up the low cost creatures to make the deck faster, which is what aggro needs.
