Hearthpwn

The goal of this deck is to make one gigantic Spirit of the Shark that can smack the opponent in the face and act as a big chonker taunt if you don't kill the opponent outright. With cost reduction in the form of Scourge Illusionist, Rotten Rodent, and Shattershambler, you can reduce Invincible to quite a low cost, even down to 0. The key is getting a Shark to stick for a turn (which isn't usually too hard since it is stealthed), and then you can use the Invincible battlecry to target the shark for +10/10, have it die from Shattershambler for another 5/5 (or 10/10 with Snowfall Graveyard), and it is even possible to ping off your Invincible after reborn for another 5/5 or 10/10, creating anywhere from a 15/18 Spirit of the shark up to a 30/33 shark. Will it be competitive? Possibly, but I doubt it. Will it be fun? I sure think so.
