Alexstrasza OTK Druid [Sunken City Theorycraft]

The reintroduction of Brann has allowed Malygos Druid lovers to rejoice!

The OTK is as follows: 

Reach 20 mana with Gruff

-Play Brann, placing you at 17 Mana

-Alexstraza your opponent for 16 dmg, now at 8 Mana

-Green Thumb Gardener with a 6-7 cost spell in your hand, placing you at 14 mana (Gardnerer would put you at 2, but with double battlecry you get double the mana gain)

-Zola Alex, now at 11 Mana

-Alex again for an additional 16 damage

=32 dmg

The deck is capable of dealing more than 32 dmg, as you can obtain copies of Brann/Alex/Gardnerer with Moonlight Guidance.
