Rate my Dragon Deck...?

I understand that you want to use this deck for fun, but I would suggest that you shrink this deck down to 40 - 45 cards. Blue Eyes White Dragon is a powerful dragon, but it needs all the support you can give it. Kaiser Seahorse and Kaibaman are good to help summon Blue Eyes White Dragon, but don't forget Lord of Dragons or Flute of Summoning Dragons. I would not include Armed Dragon or Horus unless you are making a Level Up deck. Good Luck with this deck.
