"Supreme King Dragon (please advise)" Deck 2017

Playing

For the time being, I got all the four dragons, so I tried to build a deck with all the four dragons.
... but as you can see, the EX Deck is completely unfinished.
But since I got my hands on the Four Dragons, even if I didn't get all of them in the duel...
If I have the desire, I would like to deploy up to three at the same time.
Goshiryu Magician and Astrograph Magician are also included.
If the timing is right, I want to summon Supreme King Dragon and try to express my greed...
Well...Hao Ryu is completely treated like a bonus this time, so I haven't given it much thought.

Strength

I've just built a combo, so I'm currently thinking about it.
Well... I feel like it's going to be an imitation of the Supreme King Dragon Deck I made before
I'm thinking of incorporating another thing with this

Weakness

The problem is... how many Link Monsters should be incorporated, including tampering with the main Deck?
It's a story about whether it is possible to deploy multiple Four Dragon Dragons at the same time.
Therefore, what I would like to request is the type and number of Link Monsters that should be included in the EX Deck.
By the way, I don't know how many Link Monsters I should put in, so I dare to set it to a small number of 7 for now.
I would appreciate it if you could change the contents of the main Deck a little.
