Few days ago I hit legend live on twitch with quest shaman running one copy of bloodlust. The guide is in the video, part 1, and in part 2 you see me hit legend on stream. In the videos you can see the winrate on the deck tracker, so the title is not a clickbait. Sample size over 30 games. Sorry for this small sample size, but it's not bad either.
