Adventure Priest (Tempo Corrupt Priest)

[6/23 update: Seems legit against SMOrc! 8-0 vs. Shaman, 3-0 vs. Hunter; overall 12-2, with losses coming vs. Clown Druid and Deathrattle DH]

I've loved playing this deck! You still get to experience a bit of everything Priest (resurrect, discover, heal, steal, discount), but your opponent doesn't suffer as much if you win. Not yet sure just how good this deck is, but it's definitely a lot of fun and is competitive against Shaman and Hunter!

When playing this deck, just remember: tempo, tempo, tempo. You want to try to be ahead on board as much as possible--you're a tempo/initiative deck, not a late-game value deck. That means getting on board as soon as possible; one of the big weaknesses of this deck is it only has two turn 1 plays, so you want to hard mulligan for Meeting Stone in most matchups (I've tried adding other 1-drops, and none of them feel at all worth running, even though the deck desperately needs 1-drops).

Try to curve out as much as possible; use your healing cards to take value trades and take firm control of the board. Condemn (Rank 1) and Blademaster Samuro are in the deck as a "break glass in case of emergency," but you'd rather spend your mana developing initiative rather than reacting to your opponent's board.

Dark Inquisitor Xanesh and Archdruid Naralex aren't must-keeps; they're fine to keep in slow matchups, but in fast ones, they're likely to be dead cards till around turn 6 or 7, at which point you should already be winning. Naralex is there almost exclusively for slower matchups (in faster matchups, he's just a last-ditch effort at generating a board clear or extra stats for Samuro or an Apotheosis minion via Nightmare). Renew and Palm Reading serve a similar role; their respective jobs are to heal your minions to secure value trades and to enable quicker board clears/try to find an answer for a desperate situation. They're utility cards that you want to throw back in most matchups.

Cabal Acolyte + Wave of Apathy is excellent against heavy decks and other tempo-based decks (Acolyte + Raise Dead is an especially effective counter against a turn 3 Arid Stormer), but again, you don't want to keep them in your opening hand against faster decks (even if you have the combo) unless you also have cards that can help you contest the board (for example, going second and hitting the perfect curve of Meeting Stone, Wave of Apathy, Fairground Fool, and Cabal Acolyte).

A final word: I'm still learning this deck, and I'm not settled on several cards (Renew, Condemn (Rank 1), Auspicious Spirits). However, I have been enjoying a decent amount of success with this list at Diamond 3 and 2, and I think it feels less toxic than Control Priest, since you win with a proactive game plan rather than with probability manipulation and removal. Wouldn't necessarily recommend it for a legend climb, but if you don't care too much about winning (I'd guess this is low to mid-tier 2 in the hands of a good player) and want to try something new, take it out for a spin!
