This is the Neviilz Dragon Murloc Rogue Deck w The Curator he was playing on stream. As you’d expect with a Neviilz deck, there are some interesting card choices in this deck.
This deck has all of the Mill Rogue mechanics to mill your opponents out. The Curator helps you draw those Coldlight Oracles. The main reason Mill Rogue loses is when you don’t draw these early enough. You still have to wait until turn 7 to play The Curator but at least it’s a guaranteed draw with a Taunt at that point.
It’s a fun deck to play, give it a try and see how you get on.
