MTG Salvation

Hi! I am currently trying to build my first Commander deck and I would like to hear what you think about it (aka i need some advice)

I already made two version of my ideal version, both extremly unbalnced. The idea behind the first version is to draw a lot of cards. You draw, draw draw (while you keep playing lands and farming mana) and eventually the dragons combo will start.
With dragons combo I mean:

1. you have something like dragon's hoard or Vanquisher's Banner in play
2. you put in play dragons like Utvara Hellkite or Nesting Dragons or Broodmother Dragon (and so on, view the list below)
3. at this point you keep drawing a lot, even more than before because now you have a lot of dragons that keep being played or attacking (the commander is The Ur-Dragon) which helps you to keep drawing
4. At this point it is done. Eventually you will draw Door to Nothingness and your opponent will loose because of it, if you are not able to win thanks to the incredible amount of dragons you have in play

You may think that i am forgetting about the mana, because yes, what i want to do costs a lot of mana. The point is that by drawing a lot you will never miss a land (and playing lands will make you create a dragon token, draw) and you will be able to cast creatures like bloom tender or birds of paradise.
To keep it short, in my test the problem never was the lack of mana, but I am very open to your suggestions

Here is the deck:

The commander is obv The-Ur Dragon. As you can see the number of cards is 96, because i can't find the other four, another point where i really hope you can help me.
I really like the idea of creating a lot of mighty dragons (tokens) but there aren't a lot of cards that let you do that, so i'am really trying to find that cards in the deck while playing, and this is the reason of the very storng "draw thing" in this deck (basically i want to draw the dragons that let you create dragons token)

As I said before i am a total noob yet so I am asking your help to create a nice deck.
You may notice that this isn't cheap, so if you can point me some cards that will do the same work for less money, well i will love you even more.

Thanks for the help

p.s yeah, the name of the deck is copied from the Rhapsody's song
p.p.s I belive this is the right section to ask this kind of things, I am sorry if i am wrong

Sorry for the late response. Could you please sort your decklist by card type (i.e. creatures, lands, sorceries)? That would help a lot in evaluating your deck and how it would work out.
