It's usually easier to do Prophet Velen + Embrace the Shadow + Mind Blast + Flash Heal, but requires a turn of Emperor Thaurissan to get working (6 for velen, 1 for embrace, 1 for each mindblast, free flash heals). 

Woops haha i kinda got mixed up but yeah thoughtsteal saves the day, but the paladin would need to actually run the damn thing and it would need to be in their deck rather than hand, even then its a low hit chance to get that specific card. My bad.. lol

The actual worst?? Lol. I was just fixing the previous combo which something that could actually work, I'm not advocating this should be run in Wild. But really, the worst???? I can think of worse.

I can Circle AND not play or damage my Auchenai Soulpriest?  If I do not pull one, I'll at least craft one.  Can't see running two of these when we would have two Soulpriests in the deck.

Corrupted Healbot isn't looking so bad now, is it? This card is a game changer!

Prophet Velen + Mind Blast + Embrace the Shadow + 2 Flash Heal = 30 damage (13 mana trought, need to Emperor Thaurissan 3 of 5 cards at least)

I detest shadow priests already - this just makes it worse. At least they have an excuse to use the deck now, other than one gimmick card.

Soon young ones

Without thinking too much in-depth about it, Auchenai Soulpriest is a 4 mana card that people are willing to put on board to combo with Circle of Healing knowing that the body will vanish the following turn. Using this on turn 2/3 to guarantee a board clear or combo later in the game with a follow up minion play is incredible.

Anti yogg-saron synergy or Positive Synergy?

Feels like this should draw a card or have some other effect as well.
