Obelisk Beatdown

I tried to make a custom deck myself but seems to have alot of trouble.



It's objective is to spam lvl 8 dragons for xyzs, and sacrifice for obelisk when you draw it. But it has lots of problems.

-Lack of Consistency
-Dead draws
-gets smacked by backrow

I can't seem to find the balance in these 3 things for this deck so any help would be appreciated.
