MTG Salvation

So up until now I've been playing magic with the sort of mediocre mentality indicative of those that have potential yet deign to not excel. I've been beating scrubs over and over and this has contributed to my thinking that I'm actually much better than I really am; this has got to stop because I've been stifling just under 1800 for the past month or two when I know full well I am capable of breaching that barrier.

I have constructed a decent Doran Rock deck as such:


The main problem is that I never spent the time (in both deliberating on card choices when actually constructing the deck and in asking you fellow forumites for advice) and have made the deck just before my EXT tourneys actually began.

Another problem is that I am quite limited on resources what with having no job and parents hit hard by the economy. I have most of the competitive cards from the LOR-SHA megablock and precious few cards from CON onward and stuff pre-LOR. These are the relevant cards I have available:

4 Blossom
2 3Sphere
1 Sword of L & S
1 Sword of F & I
2 Loxy Hammer
4 Hyppies
4 Colossi
2 Elspeth
4 Cloudthresher
1 Profane
4 Primal
4 Wrath
4 O-Ring
4 Infest
4 Crib Swap
1 KoM
4 Putrid Leach
2 LftL
3 Raven's Crime
1 P. Arena
3 Teeg
4 Pools
And I am also scrounging around to the best of my ability for cards like EE (which would help loads, I know) and Jitte and Maelstrom Pulse. Bobs are a bit harder because no one I know personally has them; the same deal with Hierarchs and Witnesses.

My meta is currently aggro-dominant with precious few control running around. Notable decks are 1-2 Affinity, 1-2 Bant Aggro, 1-2 Zoo, and 1 Elf with promises of Fae (hasn't showed itself yet) and a rumor of TEPS. The rest are homebrew varieties led by Hypergenesis Storm and Bloodbraid Aggro (with Groundbreaker) and T2 decks like WW Kith and Blightning Aggro.

Now, given that load of text you may or may not have completely read and digested, what would you do to maximize your chances to win given my circumstances?
