Not amazing, but decent. Can be used to remove disruptive cards from your deck and/or enable the new pure paladin cards. Maybe you can create extra card value by somehow shuffling neutrals into your deck.
A good card for a Dragon Priest deck. It has good stats and it only damages enemy minions. The downside is that it doesn't have taunt so against aggro decks it can be ignored. Maybe you play it after clearing the board?
It will be an obvious staple if purity paladin somewhat becomes a thing. Can't wait to test it in wild and pretty happy to finally see a set that might shake up the meta.
It's a good card that fits on curve on a Thief Priest with Galakrond and Princess Talanji. If you play it on curve it'll be easier to guess the card. If your opponent have lots of cards it'll be more difficult.
New Neutral Minion - Hot Air Balloon
Good for token decks. Ok card in wild for mech decks too.
New Warlock Spell - Nether Breath
Very strong with healing effects that can go face.
New Neutral Minion - Parachute Brigand
Aggro Pirate Warrior for the SmorC! Free cards are always welcome.
New Warlock Minion - Dragonblight Cultist
OK invoke card, 1 health is too painful to see play.
New Neutral Minion - Tasty Flyfish
I don't see this card getting play at all. This murloc dragon thing seems quite rare.
The art design it's pretty great. The flying murloc it's pretty cute.
New Warlock Minion - Crazed Netherwing
Strong control card and a better duskbreaker. Turn 5 seems reasonable.
New Neutral Minion - Evasive Chimaera
Arena card. There are much better 2 drops for standard.
New Warlock Spell - Dark Skies
Not enough support for handlock to make this card work well.
New Warlock Minion - Veiled Worshipper
Good fit for Galakrond Zoo with the decent stats.
New Priest Spell - Whispers of EVIL
I don't see a reason to run this card in any Priest deck. Why would Priest have a lackey?
New Warlock Minion - Valdris Felgorge
Unique effect. I'd like to see more tools for handlock.
New Priest Minion - Disciple of Galakrond
Great 1 mana minion that invokes Galakrond. Priest decks are looking pretty fun to play.
New Warlock Hero - Galakrond, the Wretched
Interesting to see it being zoo based. Random demons are just not consistent.
New Priest Spell - Grave Rune
Great card that will allow some insane shenanigans. In Wild it's an awesome addition to Quest Priest.
New Warlock Minion - Zzeraku the Warped
Late game value machine, but the current control tools may not allow this card to see much play.
New Priest Spell - Breath of the Infinite
Great removal tool, excellent for Dragon Priest. Awesome in wild for the Dragon Deck.
New Shaman Minion - Surging Tempest
1/3 is already great for 1 cost, making it a great early game minion. But if you want to play aggressive shaman decks, murlocs just seem better.
New Neutral Minion - Wyrmrest Purifier
Not amazing, but decent.
Can be used to remove disruptive cards from your deck and/or enable the new pure paladin cards.
Maybe you can create extra card value by somehow shuffling neutrals into your deck.
New Priest Spell - Time Rip
Awesome removal tool for Galakrond Priest decks.
New Shaman Spell - Invocation of Frost
You play this for the invoke but not for the freeze effect. Overall balanced.
New Priest Minion - Chronobreaker
A good card for a Dragon Priest deck. It has good stats and it only damages enemy minions. The downside is that it doesn't have taunt so against aggro decks it can be ignored. Maybe you play it after clearing the board?
New Paladin Minion - Lightforged Zealot
It will be an obvious staple if purity paladin somewhat becomes a thing. Can't wait to test it in wild and pretty happy to finally see a set that might shake up the meta.
New Priest Minion - Envoy of Lazul
It's a good card that fits on curve on a Thief Priest with Galakrond and Princess Talanji. If you play it on curve it'll be easier to guess the card. If your opponent have lots of cards it'll be more difficult.
New Shaman Minion - Squallhunter
+2 spell damage is great with a solid body, hard to evaluate the overload effect though.
New Shaman Spell - Storm's Wrath
Token style decks (Thunderhead) will love this card. It can fit in murloc decks as well.
