I'm a killer dragon master. I would also like to know your main monster in this. A good way to learn about dragons is to start with a dragon structure, like Hieratics or Dragunities. Could even go for a basic Azure Eyes deck. The possibilities are endless. Are you wanting more spam or field control? Do you want draw power or summoning power? XYZ or Synchro or both? Would you be willing to drop the fusions? Very important questions.
I mean no offense here when I say that this deck has like 0 power to it. Victory comes from your draw luck, and since you have a 50 card deck, it comes down to like a 15% chance of drawing what you want on your first turn. Below are some deck ideas you might want to convert this deck to.
https://i.imgur.com/y8oxjie.png - This is a maiden blue-eyes deck. Very destructive. Has good draw power, good def, excellent offense, field control power, dragon safety effect, and so much more. Takes little to nothing to use. I could teach you how to use it.
https://i.imgur.com/AksNGyD.png - This is a basic Maiden bonus Heiratic deck. Best suited for field control. Has a good summoning effect. Ability to summon a 4500 atk monster on your first turn if you're hand is perfect, which is 75% of the time. Takes a little practice to master, again, I can teach you.
If you want any more, just ask. Got loads here.
