More lazy mana cost nerfs, most of these are ether overkill or wont really change the issues people have with the cards. Big Priest is still going to be cancer in wild, Dr Boom is still insane, just a little slower, control warrior has more then enough tools to manage afew extra turns before popping him.

Sigh

True enough, but your paying 10 mana for a card that will do nothing the turn its played, and if you that far ahead that you could afford to do that, you would of almost certainly won the game anyway.

Doesn't even have taunt or anykind of healing too help defend you for your huge investment.

Undertaker pre-nerf.

If we have to count the cards as they stand today, thats a much harder question, there are cards that enabled a whole new set of archtypes such as reno etc. So their impact was certainly up there, but in terms of power-level I dont think they quite cut it.

I remember mysterious challenger secret paladin was horrifying, and still dominated wild for years after he rotated out due to cards like avenge. 

I honestly think you have to count Baku up there as well, Odd paladin is just monstrous and is the number 1 deck in wild atm, not too mention the many other tier 1 decks Baku enabled.  

A criminal lack of mention for means streets of gadgetzan, this is the set that gave us pre-nerf patches, resulting in virtually every aggro deck suddenly shoe horning as many pirates into their deck as possible, it got so that Bloodsail Corsair was seeing legit play in attempt for these decks to tech against each other.

At the other end of the spectrum you had jades, most notably jade druid, which was a simple insta-win vs any control deck, the single reason every control deck had to start teching giest.

And then lastly somewhere in the middle we had raza reno DK preist, dishing out 6-8 damage, for free, every turn. 

Easily in the top 3 imo.

As others have said, mage is generally the hardest, I know its the one I also had by far the most trouble with, took around 100 bosses irrc.

Yes I played in beta (i think it was beta it was changed?, been so long) im aware of tinkmasters old effect, because a card was deemed too powerful literally over 5 years and over 10 sets ago doesnt really mean anything anymore and frankly seems like a very lazy excuse to let a card rot away forever.

Ive also read that exact article, although it was a long time ago, I think around 2010 so my memory on some of its finer points are abit sketchy, but again I'm not really refering to buffing just plain bad cards, such as vanilla stat minions with little or no text, all of the cards you pointed out have been wildly regarded as bad/poor but none of them are "will instantly lose you the game most the time you play them" quality, ive seen them used many a time to innocent enough effect by newer players.

Hearthstone has a huge, massive edge over TCG's in that, well its digital, cards can be readily changed, altered at any time, yet hearthstone has never really taken advantage of that, a card has to be pretty much breaking the game before its given a token nerf and thats all the card changing interaction we ever get. I dont understand why we should be scared of the remote chance that buffing a terrible card might make it too powerful one day, if that happens...just change it again? We have had the undertaker hunter, grim patrons, secret paladin, pirate warrior etc etc etc all the way up until the dominate decks of today, does it really matter if the next dominate deck used a card that has spend almost its entire life in the garbage bin for a bit?

Buffs are not the answer if you want a changing meta or to curb an overbearing archtype/deck, nerfs are the established go-to for that.

I don't think widespread buffs would or should ever be a thing, but it does really frustrate me the huge boatload (and yes when you add them all up through all the sets, there are absolutely tons) of cards that are just so laughably,unplayably bad, I'm talking Millhouse, Nat pagle, tinkmaster, cho, duskfallen Avinna, Hemet nesingwary  to name but a few. How does having these cards exist as they are benefit anybody, apart from giving rage to a. people who get them in packs or b. people who get them from some kind of random generation effect.

I'm not even suggesting huge overhauls or changes, often just some small stat buffs or make their often gamebreaking side effects not quite as ridiculous so they can at least have *some* level of playablity and niche, even if it is an obscure one.

Just too throw in some random suggestions off the top of my head, what if Hemet actually had playable stats so it didnt die to almost every 2 drop? You could have an tech option if beast heavy decks ever start dominating the meta, and before you laugh, remember there was a point in time in hearthstone where pirate warrior and other weapon decks were so good, bloodsail corsair was seeing play. What if you could choose the target for tinkmasters transform effect? All of a sudden players would have a tech option against the big pirests rampaging in wild right now. The possibilities goes on and on

Instead they are just left too rot and be forgotten about forever apart from a trolden video every few months when someone makes the mistake of playing one, such a waste.

Mage card is barely passable, but the rest, including this one, are so lazy. Surely giving new/budget players cards in the classic set that are even just halfway decent helps them out (due to never rotating out) way more then some hyper-RNG card they will probably just play once or twice and then cut out forever after realising how awful they are

Please add meh, all memes welcome, and Ill happily play any memes/gimmicks on request. EvilYoshi#21564 EU

Cant see it been popular, allot of people like Arthas, Uther has well met memes. Ill be sticking with my waifu Liadrin personally. 

Allot of epics plus a golden uther, gave me a nice ton of dust to finish the all golden version of my old school priest deck (nostalgia) so no complaints at all.
