Help with my Yu-Gi-Oh! deck?

On a scale of one to ten, I give it a seven and a half (7.5). You should try to add counter trap cards like Dark Bribe or Solemn Judgement these will help you. Field Spell Cards like Mausoleum of the Emperor lets you easily summon high level monsters from your hand by paying 1000 points (if its a level five or six) or 2000 points (if its a level seven, eight, nine, ten, eleven or twelve) and Fusion Gate to fusion summon easily Cyber Twin Dragon, Cyber End Dragon or Chimeratech Overdragon, those Field Spell Cards will might help you as well.
