The most overpowered card in Hearthstone is...?

[volkanik]

My vote goes to Skillroy Jenkins for neutrals, and Dark Cultist for class specifics.

[Torais]

Hard to say without context but if we have to boil it down to a single card I would say Polymorph/Hex. You get silence and hard removal in a single card far too cheaply. Both of which are from classes with plenty of control/removal already.

Wisp. 0 mama for a 1/1 now thats overpowered.

I actually watched Freegold hit legend with a wisp deck. He used the wisps as tokens for Questing Adventurers.

Shadowstep for class specific, Thalnos for neutral.

[Worgar]

while its not nearly the most powerful, i find leper gnome incredibly annoying to deal with when not playing my mage deck.

[Salech]

Luck/RNg is the strongest card.

[kail]

Harvest golem. I don't think there is a more popular card than that efficient 3 drop. This coming off of general class builds. Spider probably ties due to the abundance of hunters that appear.

In terms of combo potential, Leeroy.

[fengosa]

Ancient of lore is pretty strong and hex + faceless is a fun combo as well. Overall lock hero power probably trumps both of those

Leeroy. 0 skill card that is quite overpowered.

Skillroy.
Just had a warlock who Leeroy + power overwhelming + power overwhelming for 16 damage and 6 cost, luckily he left me on 1hp and I punished his ass for being such a skill-less fool.

Unleash the Hounds, tell me another card that will draw you 5 cards, whipe the enemy board and spawn you a 12 attack minion.
Mad Scientist is also OP, 2 cost minion with 2, 2 that draws a card worth 2-3 mana and uses it.

Why are you feeding five minions to a hunter's UTH draw machine?

If you're committing that much to the board before he's played UTH you deserve to have that hunter stomp you.

angry chicken. i mean its so overpowered that almost no one uses it. that has to mean its so overpowered people are afraid of its power.

Its actually 14 damage...

On topic, i'd say it depends on the use... Leeroy is definitely very powerful, but other cards can be just as, or more powerful than Leeroy if used correctly. Kel Thuzad being one. Webspinner too, is also powerful in its own right, it virtually gives you 32 cards, since you have the webspinner, it dies, and you get a completely new card

Strong cards costing mana is fine. Strong cards costing 0 mana is insane.

I count Leeroy as more of a meta thing, he's just having a good time now. Maybe a nerf but who knows.

[Teebone]

Inner Fire class specific. I've had a 16/16 by turn 3 before.

[Astalnar]

Definitly Shadowstep. They need to actually make that card cost one mana. Otherwise, rogues are out of control.

[Zamfix]

No card on it's own is overpowered.
