Ivory Knight has VERY good odds to heal your Paladin for at least 3. That's not gonna do a whole lot, as any actual healing you'll need done will be with a 5-mana spell probably.
Kindly Grandmother will be a 2-of in most, if not all, Hunter decks. it's got stiff competition with Swole Froge atm.
Barnes is a sleeper. There will be so much experimentation with Barnes it'll be crazy and I love it. I can't wait for him to hit because someone, somewhere, will find that one deck that runs Barnes properly, and it'll be a MACHINE.
Realistically though I don't think it'll be -too- much better than Volazj.
The Curator is a 7-mana 4/6, same statline as Ancient of Lore. It also draws, realistically, two cards; a midrange beast and a finisher dragon probably. That alone makes it just as good as old Ancient of Lore, held back only by the fact that it's a lego and you can't run two.
Ethereal Peddler is... eh. I want to believe but I just can't bring myself to really.
1-mana 2/2. they can't keep getting away with this.
Firelands Portal has roughly two bad outcomes, I checked out. There are, right now, 51 outcomes including the new peddler, and in mage the only bad "worst" outcome is the Ram Wrangler, because at least you can ping your Grim Patron. If you get a 4/5 body with this, it's already worth it.
Overall these cards are "playable" with two of them probably going to find permanent homes in decks for a whiles to come.
