Ahh the must include priest single target removal spell, never forget to include this in your deck. You can never go wrong with it. 

hmm... Now that it's 3 mana, maybe it will be playable in some king of tempo heal priest alongside Crimson Clergy? Also turn 3 Lightspawn into turn 4 Power Infusion seems interesting, but i feel like Power Infusion isn't good enough in that deck. But despit that i think Lightspawn will see play because it can now get ressed by Rally!.

Still nice to see this cheap removal, and you can still generate this from Wandmaker. Kinda interested what else you're going to be able to do with that Holy spell tag. Glad to see it still in the Core set, might see play now that Penance is rotating.

Makes one minion strong, but that's it. Also it's still easy to remove big minions with all the removal still in both standard and the core set. I don't think this will be good enough to see play.

Strong board clear, and can help heal all your minions in the tempo priest strategy. Also helps buff Crimson Clergy and buff minions if Lightsteed is on board. Solid spell for the Core set.

Hmm even with the buff it seems bad still. Aggro/Tempo priest probably doesn't want it because those types of decks rather have 4 drop minions on top of their curve, not 5 drops. But who knows, it might surprise everyone. Probably not though.

Seems good for the core set. Priest seems to get more tempo support, and Iksarr said in a recent AMA that "Any class that was draw restricted will see more card draw". Priest has always had bad draw, so that could hint towards priest getting more draw and draw is the only thing tempo priest and Silence priests need right now. So i think Kul Tiran Chaplain might be a solid card in that deck.

I'm really interested in the way there going to revisit shadow priest, looking forward to it. BUT i see that Mind Shatter is gone from the text, so that might make Shadowform a lot worse. I hope it still gives you Mind Shatter, otherwise running a second copy of Shadowform will feel kinda bad.

Very strong card if 5+ attack minions are common, and it is at its strongest in a control meta. I generally end up adding at most 1 copy of it to my priest decks, because it's more of a tech card. The meta seems like it's going to probably slow down a bit, so it might see more play. But i'm still skeptical.

Natalie Seline is a good removal card, but she is very expansive. Now that a lot of expensive priest removals are gone, maybe she will see play? Not sure though. Priest prefers expansive Board clears over expansive single target removal. IF they want to remove a big minion, they rather use Shadow Word: Death instead. The only real reason why you would use Natalie Seline is if there are a lot of evasive/high health minions in the meta. I wish that Natalie Seline got a buff/change, because she is really situational and hard to use right now.

"The idea of Book of Heroes will be expanded beyond the 10 core characters."

I like it, maybe we will get Tyrande, Maiev and Arthas eventually in BoH and get new skins for them as well? Overall i see this as a big win, BoH are pretty fun and an interesting way to learn about characters lore.

"Any class that was draw restricted will see more card draw." Okay so classes that were quite restricted in draw: Hunter, Priest, Shaman & Paladin. Hunter is amazing, because that's mainly what held back most non-aggro hunter decks. It was way too hard to draw a combo piece in hunter. Priest is REALLY interesting, because the one thing Tempo priest AND Silence Priest always lacked was card draw, so if they get good draw it probably becomes a really strong deck. Paladin is arguable, but they don't have that much draw overall. (Hand of A'dal excluded.) So if Paladin gets more draw, the decks that benefits from that the most will be Dude paladin. (Which already seemed scary) Shaman lost a lot of draw, (mainly because quest rotates & Novice Engineer isn't in core) and i'm happy to hear that they get some new draw. Let's just hope it isn't too strong of a draw, otherwise Evolve Shaman might come back stronger then ever. (Mainly because evolve effects are a lot stronger now, because of the smaller Core card pool)

THE best paladin secret ever created returns. Paladin secrets are often bad, but Avenge is not just the best paladin secret, but also one of the very best secrets ever created. It still sees play in ODD Paladin to this day and it will 100% see play in standard.

Meh, never saw play and won't see any play.

Staple in any paladin deck, kinda scary to see it back in standard. But i'm still glad it's back.

Might see play in aggro Paladin? Seems decent in terms of stats at the very least.

Buff wasn't needed, and man Dude paladin seems strong now. Also RIP Wild.

It's great to finally be able to actually play it again instead of getting it from the pure paladin card. This card belongs in Core.

Great buff that still sees play. Love seeing it in the core set!

Great card that always has seen play in both control and aggro Paladin decks. This card belongs in the core set.

Great reload for Dude paladin, and with all the dude support this can be quite a scary card.
