Waveshaper Water deck: Sharking up the Wrong Tree

Midrange-control deck based around expanding your body of water, curving out with minions, and then capitalizing on this with such effects as Mariner's Curse, Giant Shark, Anui Undine, Troll Bridge, Thin Ice, and Watery Grave

Hard-mulligan your sites to begin the game with at least one: Troll Bridge, Thin Ice, or Bottomless Pit

Hard-mulligan your spells to begin the game with at least one: Porcupine Pufferfish, Coy Nixie, Guile Sirens, Nelly Longarms

Use these effects to threaten to kill your opponent's early minions, and then trade 1-for-1 with anything Big & Greedy using Lethal minions, Iron shackles, Pollimorph, Mesmerism or Sleep/Just a Rock/Drown from your Toolbox

Use Dodge Roll/Goswhit Helmet aggressively to save your expensive minions or to disable your Giant Shark during your turn, allowing you to move your minions without threat of self-sabotage

Pretty hard to pilot but very fun; not competitively viable. Likely if you wanted to win with a similar type of list you'd want to find a way to Splash Air
