74 cards is 14 too many.
Anyway, the deck looks unfocused. You've got a Dragon theme, an Aura theme, and a bunch of cards that don't fit either. If I were you I'd try to
concentrate the deck more on a single plan.
Also, you'll probably want more cards that reward you for playing Dragons or Auras. If you've got a bunch of Dragons, cards like
Dragonlord's Servant get a lot better.
