So when Festival of Legends goes live, Core set cards will also be rotated. There's no doubt in my mind that some version of imp warlock will reign supreme, but finding the right mixture is what's going to be important here. Mal'Ganis will be back with standard and if you didn't know with combination of The Jailer will make you board *theoretically* invincible. Mal'Ganis makes you immune and The Jailer makes your minions Immune, effectively shutting down your opponent chance to win. The only counter to this board lock is Mass Aoe Destruction which I will list a few here Twisting Nether, Gigafin, Brawl, Whirlpool, Primordial Wave and Soulstealer.

For a bit more spice I also added Tony, King of Piracy so that when your minions become immune you swap your destroyed fatigued deck with your opponent's. The is one of those decks that I both want to work and hope it doesn't become meta because I can see myself having fun with this but also hate playing against this.
