Went back into the adventure and saw I only needed heroic Free Medivh and Heroic Chess. I beat this chess in two attempts by following the mulligan and positioning tips from Taiji. My first attempt was a 1/6 on 1 and 2x 1/6 on two and was cruising from there. The reason I lost was that my bishops were both on the bottom, so I wasn't able to generate value by keeping rooks and knights alive. I got him to 7hp, but just ran out of steam. Second attempt had same start but got a bishop much earlier which kept me ahead the whole game while doing 2-3 damage a turn to his face.

Good luck. Don't give up.
