This deck is from Blizzard’s Off-Meta Spotlight #5, here’s what they had to say about it:
Next up, we have Suimin’s Kingsbane-focused Rogue deck, which utilizes another Hall of Fame inductee: Cold Light Oracle. Suimin took this version of “Kingsbane Mill” to great heights on the SEA ladder, with an overall 64% win rate. Combining multiple weapon enhancements with Kingsbane’s ability to retain them, this Rogue deck is able to take exceptional advantage of the removal cards that rely on having a weapon. Suimin’s deck can be challenging to play, with some truly awesome interactions that’ll demand mastery of its ins and outs, but the learning process will be tons of fun.
