This is the Neviilz Shadowcaster Yogg Rogue Deck he was having success 
with on stream. it has all the typical staple Rogue cards, along with Yogg-Saron for that late game crazy win-condition.
Don’t blame anyone other than yourself if Yogg kills you. You sign up for anything to happen when you play Yogg. Although, when you play it on a board you are behind on, it’s more likely to help you then kill you.
Shadowcaster is an awesome card. You can add a 1/1 to your hand of SI:7 Agent, Xaril, Dark Iron Skulker, Emperor Thaurissan, they all offer insane value.
