Building Fire Lord Azula to the highest power I possibly can. Would like honest feedback and constructive ideas.

This is my first attempt at building my own CEDH/B5. The idea is a control heavy midrange that generates a large burst of mana for it's win turn to force through multiple copies of thassa's oracle and tainted pact as a victory condition while still having enough shields left for any potential counter war.

Big concerns I'd like help with are do I have enough draw? And the land base is shaky, what do?

Deck is to play at my local game store on their competitive nights, this means I can't proxy so don't have the dual lands or wheel.

Willing to buy any sub $50 cards I need next time I get paid. Especially if they are staples of izzet or grixis in cedh.

Is this even vaguely viable or should I just go rog/sai, Vivi or Ral and learn to pilot them instead?
