If I recall correctly first 18 buffs gave you full refund

As Lataberk correctly stated, we got full refund on buffed cards last time...

What are you talking ? We didn't got refunds for the buffs.

"Will there be dust refunds for buffed cards?

• Philosophically, cards that we feel we’ve improved won’t be eligible for refunds"

I'll be boring and say that they undo the nerfs that would have the least impact:

Wild:

1. Bonemare: I think most decks have better options to consider anyway.

2. Spiteful Summoner: Way more lowrolls possible than we used to have in Standard, and such decks are unlikely to succeed in the format.

3. Call of the Wild: Still "fair" for 8 considering the rest of the format, and maybe they'd like to buff Even Hunter a little (which some people already try thanks to Phase Stalker and Dragonbane).

4. Yogg-Saron, Hope's End: A fan favorite, highly requested, difficult to include actually, and if you want that crazy spell explosion, you should have it. There are more unfair things you can do for 10 mana.

5. Tuskarr Totemic: A random free Totem Golem is probably still really good, but worse than what some decks can do consistently, especially as Shaman.

Year of the Raven:

1. Dr. Boom, Mad Genius: Was arguably too good for Standard, but not for Wild I think.

2. Extra Arms: Same as above.

3. Reckless Experimenter: SN1P-SN4P can't be played for less than 1 anymore anyway, which makes this nerf kinda pointless.

4. Giggling Inventor: Tough call, but there are not many other candidates left, and this would arguably be less impactful than Raiding Party and Luna's Pocket Galaxy. 

Year of the Dragon:

Invocation of Frost: Most of the nerfed cards from last year are still used or decent enough, except for the Shaman cards. And with Zentimo leaving, I think this one is the most likely candidate.

Again, this is just what I think will happen, not necessarily what I'd like to see happening. And if they wanted to take this opportunity to shake things up, my picks would be Raza the Chained, Undertaker, The Caverns Below, Call to Arms, Spirit Claws, maybe Raiding Party, and Dragon's Pack. But I think it's safe to assume that they don't want to do high impact changes.

My guess on the Dragons card is Mogu Fleshshaper. It interacts weirdly with Evolve effects, and I'm of the opinion that it's better balanced at 7 mana base than at 9.

i think its best balanced at 5-6 mana, just because of evolve effects. its a disgusting card when evolved, pretty meh without.

The most reasonable and that does not damage the design much or be a strong interaction, my predictions are:

Year of the Dragon

Sludge Slurper

Year of the Raven

• Giggling Inventor
• Reckless Experimenter
• Extra Arms
• Dr. Boom, Mad Genius

Wild

• Shadowboxer
• Bonemare
• Call of the Wild}
• Spirit Claws
• Undertaker

and my guesses are:

Saronite Chain Gang (now that shudderwock is no longer available for standard)

Dark Pact
Leeching Poison ((now that there is a possible counter to Kingsbane)
Yogg-Saron, Hope's End

Raiding Party
Reckless Experimenter
Extra Arms
Dr. Boom, Mad Genius

Fiendish Rites

Notes:
-Level Up! is also much weaker than [card]Quartermaster[card] but reverting that nerf may cause odd paladin to be too powerful.

I think I forgot
Giggling Inventor
in the possibles list. :D

cant edit my comment again unfortunately

I think Giants to wild and Conjurer's Calling back to 3. 

Leeching poison is not gonna be changed. That would violate their idea of class identity now.

 Dark pact would be very strong in the current meta, so unlikely. Tuskarr.... they already forgot that card’s experience

 I guess giggling, Yogg, spell stone, and the rest I’m too torn :)
