Y PewPew Sac
This deck is delightful! It's a mashup of Y-PewPew with Y-Sac. In some games it plays as a rush deck, and in some more a midgame.
The basic idea for it is that there are a lot of cards that give you both a creature and an event for a single card (Hold the Line, Cartographer, Outland Ranger, Intrepid Explorer, Royal Judge). The various 0- and 1-cost events can be used to buff Windstorm Archer and quickly discount Windstorm Colossus. At the same time, the various small creatures are sac targets for Demon Wrangler, Death Walker, and Shaytan Assassin.
Cartographer enables some extraordinary turn 2 plays. https://cdn.discordapp.com/attachments/150508656184524800/540786796380815371/PewPew_Sac.png
The deck is occasionally fast enough to landlock your opponent (though not as effectively as with a Wind Gate deck).
So far, the deck is 18-12 on ladder.
