This is the Savjz Bog Champ Concede Control Shaman list Savjz was playing on stream after seeing Frodan killing it in SeatStory Cup V.
This deck is going to be popular for a while on ladder as it does a good job of countering most decks. It’s a strong control deck that can out last other control decks, and it has the damage and board clears to put a stop to aggro decks.
Give it a try and see how you get on. It’s not a simple deck to play, but you will get the hang of it with a few matches.
