This is the Savjz N’Zoth Rogue Season 29 he was playing on stream. Savjz 
is one of the most popular streamers and uses some interesting decks. He doesn’t just play the top tier decks, and does really well with a lot of his lists so it’s always worth trying out his decks.
This deck plays out like a lot of Rogue lists. Use your removal to keep the board clear early and try to get some minions to stick and value trade while fighting for the board.
Save you coins and cheap spells for a miracle turn with Gadgetzan Auctioneer to draw through your deck and find the cards you need to get value from N’Zoth on turn 10.
