Hearthpwn

It requires all 10 Hero Powers, but you can't discover the rogue one.

So you would need the Yoink! Spell on another class. Built a mage with a lot of discover, but only discovers Mage-Spells..

Another idea would be the card which copies (and draws the card for the opponent) a card from the opponent. But due to the fact, that achievements are not possible with friends, this would take forever and a ton of luck.

Really disappointed.

I completed this achievement in wild with Majordomo Executus and Anka, the Buried. Majordomo will replace your hero with Ragnaros who isn't considered a Rogue. Anka isn't technically mandatory but it certainly makes it more reliable since you can play domo on 6 and backstab it followed by Yoink! rather than having to survive until turn 10+.

I also included the Tess Greymane combo with Cloak of Shadows to use once your hero is replaced with Ragnaros and have played Yoink!.

Got it in my first game with a lucky Tess.

Good luck!
