hmm try adding in different demension dragon, and dragon dwelling in the cave. kaiser sea horse would be a great advantage aswell for your blue. a good adition to your deck would probably cards from the new structure deck dragons roar when comes out

Wow, not to be a mean person but do you acually win with this deck?? Also you know that is itsn't tourney legal (You need 40 cards).

Try trimming your tribute monsters to 2 or 3 (2 Tyrant Dragon & maybe a Mobius).
As for Level 4 and lower mosters try 3 Lord of D., 3 Spear Dragon, 3 Luster Dragon, 3 Mirage Dragon and the basic staple monsters (Breaker, Tribe, Sinister).

Use 16 spells (Look around for basic staple spell cards), you can check my sig for good spells (Smashing Ground, Premature Burial Etc...). Use only 6 or 7 traps, they are up to you mostly likely good dragon ones and cards like Call of the Haunted, Magic Cylinder and Ring of Destruction.

3x Blue Eyes White Dragon
1x Polymiztion
1x Lord or the D.
1x Flut of Sommning Draogon
1x Armed Dragon LV. 5-7
1x Blue Eyes Ultimate Dragon
1x Blue Eyes Shining Dragon
2x Jugment of Anubus
2x Cats Ear Trib
2x Change of Heart
2x Minatrizer

There is more, but they are hard to get, but i have thes cards except Blue Eyes Ultimate Dragon. Trust me I put these cards in my deck ect. with those and I never lose by the way get the Cats Ear Trib. ATK/200 DEF/100 EFFECT: When your oppent attacks it the attacking monsters ATK decreses to 200 ATK points.

ps. If you need a trad talk to me I have lots of cards.
