Based on other lists I've been seeing for the Druid. You wanna keep Tawny out as much as possible and then eventually hit one of your big creatures like the Kraken, Worms, or Great Old One with a Shapeshift and then you can also get another copy with the Simulacrum. In total you could get up to 32 power on the board for 8 mana.

Drums of Doom is kinda crucial to have on hand when the Druid flips...

First tournament today went 1-2. When the deck works it WORKS, but wasn't fast enough against an aggro Witch deck and suffered against the other decks that want there to be a lot of water. Ideas for fixes:

Dropping the Conqueror Worms and the Salmon of Knowledges for maybe some Drowns, Riptides, or Geysers if I want spells. I am going to keep the idea for a Tufted Turtles or Deep-Sea Mermaids on the back burner as I do have plenty of creatures. I am leaning towards the Drown for added resilience and removal against more aggressive decks and decks getting too much value off artifacts.

This also could clean up my lands. I can drop the Aqueducts and the Caerlon-Upon Usk for another Pond (GOATed) and maybe some Summer Rivers and Winter Rivers, or Troll Bridges and Undertows

So to clarify the first change is:

~Spellbook~

-2 Salmon of Knowledge

-2 Conqueror Worm

-2 Bridge Troll

+3 Drown

+3 Tufted Turtles

~Atlas~

-1 Caerlon-Upon-Usk

-3 Aqueduct

+1 Pond

+3 Undertow
