Teferi's Big Blue (EDH / Commander)

The basic plan is make a lot of mana, play big things, and control enough to win. Teferi helps draw more cards when out or untaps big mana producers for even more mana.

How will the deck win?
Hitting you one or more big threats. This is almost a detail as the goal is to first establish Mana advantage by Teferi's untap and Card advantage via big draw spells. Then get control, then play the big threat(s).

How will the deck draw cards?
Teferi draws cards. The deck can abuse having a lot of mana with X draw spells. It can also use tap draw effects to synergize with Teferi's untap.

How will the deck stay alive?
Lots of removal, counters, bounce.

How will the be resilient to disruption?
Lot's of card draw to recover.

What are the deck's major weaknesses?
(Should check Tapped Out gameplay logs.) Can't recall many. The deck doesn't have a lot of direct permanent removal, and obviously uncounterable/anti-blue hate will be fairly effective.
