Play a strong midrangy mono water decks

Shelly coats, failed abominations, tufted turtles are poison nova resistant, as well as our warded minions. Build pressure with these good water creatures while SEERING for island leviathans to keep super pressure, and added deep seas and annual fairs to activate him early!

Having great success with this deck,

Its very easy to mulligan for our preferred sites, and we want to play first, as the Seer we can scry for Island Levianthan, Annual Fair, Deep Sea, or Flood plain (Burea of Occult control/Garden of Eden are depending on match up)

Assuming we have 1 Island Leviathan, we ideailly want to play it turn 2 in front of us, turn 1 we can play an annual fair or deepsea flood plain. (Flood plain works great adjacent to an annual fair or other non water site, becuase we can flood it to add to our threshold to pump our Island Levianthan. By turn 4 we can easily activate our island leviathan if we have an annual fair by paying 4 mana for 4 water threshold, and because it transforms, it doesnt have summoning sickness. Kinda like a charge 8 power minion.

Only downside is we do lose a mana for our next turn, but if our opponent doesnt have an answer we pretty much win the game, turn four we can play a Selfsame Simulacrum, Sacred Stagg, Failed Mutation, and just keep hella pressure

Need to fine tune a bit, but this deck is playing better than expected and most people dont expect a turn four annual fair pump to Island Leviathan.
