Help with my deck

So I got like a 10 on the placement exam and was placed in slifer, since then i've been working on 2 decks to try and win some dp so i can retest. Sadly I realized that the decks i originally had were very unbalanced and suckish and in order to win dp i would have to win some shadow duels, and since I only have 100 I cant afford to lose. So I would like for you to rate, criticize, and give me some suggestions on what i should change. Also please give a reason why you think i should make these changes

Thanks for your time ^.^

I dont really use the side and extra decks, and to fuel graveyard, and banished zone

always good to have a good side deck so your ready for matches, always good to have a 15 card extradeck so your ready for more things, and that is a terrible reason to use lightray grepher

can combo grepher with wyverns eff to get diabolos/truth to hand +2 light(sworn) monsters to grave. Can combo grepher with light of redemption to get any card in my graveyard to my hand. Warrior fuel for reinforcements and gearfried

and any suggestions on a side deck with extra deck? criticism without advice is hate.
