Hello.
So first off, your mana base needs some adjustment. It looks like you might need a few more lands that produce blue mana and less lands that produce black.
A major issue is that all of your Dragons cost a lot of mana. By the time you get one out, an opponent is likely to have made quite a bit of progress. Running a five color deck doesn't help either. Even with the help of
Artificial Evolution and
Didgeridoo, I can't see your deck lasting very long.
While I don't think the deck will work, hopefully you will be able to tweak it. Best of luck!
