This is the Cipher Karazhan Control Warrior w Ironforge Portal deck he was playing on stream and laddering up with some long win streaks. Control Warrior isn’t for everyone, the games are long, mistakes can ruin everything, and the mirror matches are resident sleepers, but they are strong decks vs almost all matchups.
The Ironforge Portal is a much better card than most people anticipated. Fatigue is one of the problems Control Warriors face, having a random minion and some armor without drawing a card like Shield Block does is another tool in the deck.
This is one of the strongest Control Warrior lists for Season 30, and with no more new cards for a few months the lists are going to look similar to this for a while.
