This next batch of card reveals finally has me really excited for the expansion.

Deathrattle: Add a random class card to your hand (from your opponent's class)
Wow N'Zoth would be obscene in Stalagg/Feugen Renolock. A card that actually anti-synergizes with Dr. Boom, since the Boom Bots can pollute the Deathrattle graveyard pool.
Back to Standard, I wonder if this will do anything to boost a Deathrattle Rogue. There is the idea of Shadowstep on C'Thun, but it works on N'Zoth as well without having to play vanilla-ish minions. Similar to Anyfin, the second play of N'Zoth will summon any Deathrattle minions summoned the first time in addition to the original ones.
Apparently it can summon any minions that have Deathrattle inately in their card text, even if they were silenced (but not if they were transformed). Does not resummon cards that received Deathrattle buffs from other sources. Summons randomly if more than 6 Deathrattle minions have died.
I think Renounce Darkness is really cool for Renolock. Essentially an Elise Light, it helps Renolock during fatigue wars. Late game, you can turn that useless hero power and those useless Warlock cards like Mortal Coil and Demonwraths into maybe-less-useless stuff. But early game nah, I want to keep my Hellfire and Shadowflame.
I wonder if Renounce Darkness can also spawn any new archetypes. Maybe a class card heavy aggro/zoo deck that can do a total paradigm shift against otherwise unfavourable matchups.
For the Rogue card, well the value is there. But, "will it blend"? Successful Rogue decks have so far been all about tempo, flexible burn, and/or combos. This doesn't fit too well into those styles of play.
