Any hint how to defeat Bolvar?

Mul for demons to get Anatheron out as early as possible. You only need the removal later when you have Anatheron. The idea is to use your removals to clear the way in the end game so your minions can hit face.

If Im not mistaken, there's 2x Twisting Nether, 2x Hysteria, 2x School Spirits, 2x Cascading Disaster, 2x Soul Rend, and 2x Dark Bargain. Rest are demons.

Dont hesitate to use Hysteria even if you have a board. Anatheron has too much health to ever die from it, and it can remove some minions so yours can hit face. If you have twisting nether early, just play it. you can never play it when Anatheron is up.

This one is fairly straight forward, I honestly think the hardest battle is against Xyrella. As long as you get Anatheron up early you shouldn't be losing because Anatheron can easily stall until you get enough removals for the finish.

done tks - didn't realize how strong is Anatheron !

It took my two tries, and I never even freed Anatheron when I beat him on the second try.  Mostly just clearing the board with as few resources as possible.  I actually got to the point where we were both in fatigue and his hero power wasn't pulling anything.  I think my last turn I might have actually freed Anatheron right before lethal with another minion in play.  Not sure how I made it work without Anatheron to help with clearing the board.  I just got lucky I guess.
