With the return of N’Zoth and Sylvanas, Rogue may naturally want to take advantage of its Deathrattle synergy – like Anka and Necrium Blade – to get some damage done. There are two potential routes I see for making this work.
The first is a grindy style of Fatigue Rogue. The primary combo this deck operates off in N’Zoth and Togwaggle’s Scheme. Board after board of health-restoring taunts keeps you in the game as your opponent eventually runs out of ways of removing it. All you need is a single cost-reduction tick off of Emperor Thaurissan on either on your combo pieces and you can play both in the same turn.
The entire deck is built around either cycling towards this combo, staying alive, or playing Deathrattle minions to fuel it. We play Novice Engineers over Loot Hoarders because we don’t want our N’Zoth returning too many draw deathrattles when we could get heavier hitters.
This deck is likely going to require a great deal of refinement, but this is a good shell to start testing with.
