Hearthpwn

In my opinion the most annoying card is Conjurer's Calling. I can't even understand, how they could not guessed, that people would be outraged by this card. I don't even understand, why they made it a twinspell - card is broken even without it. 

I also think that mage got too much freeze. But that's another discussion. What is the most annoying card in your opinion? 

Yeah, Barnes is such a cheat as well! Big priest is just soooo annoying being vs when they get him on 4...

How are these cards not been Hall of Famed? ... Blizzard states they want to steer away from 'Charge' minions, but does nothing to the only charge minion that's still being played.

the amount of dmg + on Bloodlust is way too strong given how incredibly easy it is to fill a board, 

currently it's Convincing Infiltrator no idea why they printed this card with how much people hated Obsidian Statue. This is the epitomy of everything a hearthstone card shouldn't be. It's boring to play in that it's just a minion you put on board, and has coin-flip RNG. Once they play it and summon it back a million times with Psychopomp, it's game over for any deck that plays a lot of minions on board. Minion-trading is what makes hearthstone fun and provides a lot of skill and variety, and any card or strategy that's specifically designed to counter that should never exist. 

Any card that allow for a 30+ damage combo - Mechathun and the old mage quest are among my most hated cards. Nothing felt worst than seeing that quest pop up back in the day and just knowing that you already lost the match. 

Highly agree. That's also why I hate mage got sooooooo much freeze now.

"No idea why they printed this card" = "This is a card that counters my favorite style of play"

That said, Dr. Boom, Mad Genius is still the most annoying card. It's like being forced to repeat the same boss fight in an RPG every day for two years.

 Dr. Boom, Mad Genius

I understand your frustration. It feels even more stupid, when not every class have a hero now. 

Any value card that, when drawn and played, determines who wins in mirror matches. Barnes in Big Priest-, Dr. Boom in Warrior-, Tip the scales (drawn from a turn 4 prismatic lense) to name a few.

Conjuring Calling. 

I would probably hate Malygos not because it's a bad card,it's amazing but the decks that use it to OTK are so annoying for me

Completely not fair, and a stupid choice, but my most hated cards is Acolyte of Pain. It's boring, and the animation of drawing a card feels like it lasts a lifetime.

Brawl since first time i saw it being played

Always depends on the mode imo.

Wild: Barnes, Genn/Baku

Standard: Dr Boom, Conjurers Calling

Arena: Conjurers (Jeez, I had runs, where that card carried me hard.), Discover cards which can lead into Hero Cards (well at some time when KFT was around and Rogue was able to get another class DK in arena..).

For me, it was always The Caverns Below. I always play expansions through. I braved through Pirate Warrior, fought every Highlander Priest, and faced every Odd Paladin. All those top tier decks that beat me, I still played. Un'Goro META was the only time I stopped completely. Once you saw that Quest, you knew the game was already over. 

I guess runner-up for would be Conjurer's Calling.

Zul'jin, hunter shouldn't have this amount of value generation.
