Prince Keleseth,

Katherina Winterwisp

The entire Warlock package from Kobolds

9 mana shit your whole deck on the board priest spell. 

Hadronox (to be fair, this one got good because of Witching Hour and the insane armour package for Druid. I mean the fact that half of the strong Druid decks seemed to be memes shows how strong the core druid package was and still is.)

Hearthpwn put Zerek's Cloning Gallery in the "dust it" category in their legendary crafting guide a few days after boomsday dropped.  They even put it below that crappy 4 mana 5/4 that turns into a dire mole.

 They must be high, it can pull an Obsidian Statue and The Lich King,even though 1/1 still very powerful

Rhok'delar was initially considered crap, along with the rest of spell hunter. When Cubelock got nerfed, it rose to tier 1.

Quote from Aegis24 >>

Hadronox god crapped on a lot when it came out
Frost Lich jaina pretty much caries the mage class right now
the Entire Spell Hunter Archtype was laughed at when To My Side got revealed.

 yeah

Quote from b1ak1ce >>

Carnivorous Cube was pretty ho-hummed if I remember correctly, at least in the early days when it was first announced.
Giggling Inventor ... were obvious ones that were slept on

Thats just wrong.

Obviously Prince Keleseth and Hadronox, Crystalsmith Kangor is also nominated.

Crystalsmith Kangor always look weird to me, I couldnt't really judge the card when it is revealed. As for Prince Keleseth ,people should notice it sooner since most 2 drops aren't that good anyway.

pretty much every Dk, i remember seeing a ton of people thinking that gul'dan was bad, and tbh lock was t4 during frozen throne but as long as you can res a couple of taunts, n'zoth-like effects are really strong

Quote from Jaybaseball1 >>

In the beginning, Deathstalker Rexxar was bad... We didn't see it coming lol

 And for a very good reason, when he was released we don't have tons and tons of rush/poison/lifesteal beasts.

RegisKillbin rated Frost Lich Jaina a One Star Card. Ha.. .

 But for me it's Frostwolf Warlord after the Nerfs to Odd Paladin.

 Not a very good example.  Frostwolf Warlord was in fact played quite a lot in the early days.

Naturalize and Coldlight Oracle were considered to be cards that actively lost you the game and actually were pretty terrible in the before time.

A small commentary on some people's posts:

To be fair no one (or very few people) thought Fungalmancer was a strong card, because in the early KoFT some cards weren't nerfed yet. Raza Priest was running rampant, Corridor Creeper, Bonemare and Patches the Pirate were the stronger inclusions for odd decks.

 

 Ummmm there were no odd decks during KotFT.  Baku is a Witchwood card....two expansions later, lol.  And Fungalmancer is a K&C card...so you are kinda confused.

Friendly reminder that people rated The Caverns Below as the worst quest during the release of Ungoro.

Edit: King Krush finally being in a competitively viable deck also took forever.

 OP asked which cards are Now Meta. Not the cards that were used waaaay back in the days just after Naxx.

I remember being excited when I opened King Krush in a classic pack and a friend giving me "advice" to dust him. Glad I didn't listen to that one. Actually, same story with Crushing Walls, which was considered too situational and now every spell hunter runs it and opponents often try to play around it, anticipating it.

 This is why you don't dust anything unless there are very similar cards that fulfill the job better, like Mukla, Tyrant of the Vale and Banana Buffoon.
