This is the Chakki Control Warrior Deck List he has been using on ladder. 
Control Warrior is still a very strong and relevant deck, it’s just not played as much with the easier and faster Dragon Warrior deck that’s all over the ladder.
This deck is favored vs Dragon Warrior and a lot of the other aggro decks on ladder. The Harrison tech is a really smart choice right now too. So, give it a go and see how you get on.
