a new Priest of the Feast for priest, and a heal card for combo/control Rogue decks (turn 10 this whit crazy Gadgetzan Auctioneer madness

Sadistic Demon synergizes with Warlock's self-damaging mechanic and is good in Zoo decks, while Void Emissary synergizes with healing and has combo potential.

Note: because Fallen Hero , whose have similar effect, works on Lesser Heal + heal-to-damage effect like Auchenai Soulpriest , this should works too

proof

Peeking works similar to the old Joust mechanic. The card is shown in a small animation and then returns to the deck.
