I'd find a way to get Pillar of the Paruns in there...no reason not to, really. Or if it's too expensive, at least put in some Terramorphic Expanse. I also agree with using more creatures. You have 14 spells that target your guys and only 12 creatures! I'd cut Double Cleave (or replace it with Psychotic Fury) and Shielding Plax and put in some decent creatures (I'd cut the Witch as well). No Woolly Thoctar?
I'd drop the Traces of Abundance for Steward of Valeron because both can accelerate mana, but you need more bodies for an aggro deck; I'd want at least 20 creatures with so many auras.
Reborn Hope needs to go. Your deck is redundant enough that you don't want to take time to add WG to the cost of a dead card rather than just drawing another card off the top to play immediately. With so many permanents in your deck, Reborn Hope is often going to be dead (you certainly don't want it in your opening hand!).
I'll second Knight of New Alara, The thing is an absolute beast and the only reason it's not worth more is because it's easy to kill. slap a Shield of the Oversoul on it and you're almost unstoppable.
I seem to have left out the detail that this was a budget deck, and thus some of the suggestions are immediately off-limits. Double Cleave is better with +3/+3 rather than cantripping, and ToA is more for color fixing rather than ramping.

Jund Hackblade, Bant Sureblade, Kitchen Finks, or Wooly Thoctar would all be decent creatures to add to the deck.
