Hearthpwn

Deserving of a nerf.

I can't think of a "Rest of game" condition that was actually enjoyable to play against.

Really?

Maybe it would be better if damage was shared with the opponent instead of fully put on them?

Tamsen herself says "Share my pain" and the animation for both players is the same.

I think warlock had enough healing cards to still make it interesting!

I don't even really know how you'd make this fair.
Make both players take damage instead of just the opponent?
Really a card that puts Blizzard in a corner.

Regardless, the card is so good, all I see in ranked are warlocks now.
Grinds all the variety and enjoyment the game offers to dust.

Yeah.. Thanks Blizzard..

That's what I'm talking about

This card has gotten me out of lot of sticky situations

This card has easily been the most fun I've had in Hearthstone in a good while, absolutely adore it.

Nah, don't feel attacked mate, I'm just having a giggle at how Blur, one of the most unseen and situational cards, is number one and Tickatus, the most impactful and universally hated legendary currently, is number 17.

That IS assuming that these cards are listed in order of investment in your opinion.

There is a reason Blur doesn't see play.. It does little to nothing on its own.
If you're scrapped for cards, and desperately need some good draws to keep the game going, pulling this is a nightmare.
Especially if you're trying to get some good draws from Skull of Gul'dan for instance.
This card just doesn't do enough for a class as active as Demon Hunter.
It can't be used for anything outside its niche purpose, and even then, it accomplishes nothing on its own.
It requires the aid of other resources to be useful at all.
It's just a slow, dead-hand card that doesn't fit with how active Demon Hunter needs to be.
I'm just surprised you put Blur down as a problem card when Relentless Pursuit exists.. 
A card that essentially serves the same purpose, but actually able to accomplish something on its own with a bit more flexibility.

I won't go into detail on every item on this list, and I believe there are some valid contenders here, don't get me wrong.
Just some.. Surprising choices too.

I'd suggest putting Blur lower on the list so it's not the first thing people see since that's a particularly controversial opinion.
Gotta warm the people up.

Where my boi Lord Jaraxxus

Remember the name

Yeah, he's a real pain to play against.. Not really anything you can do to stop it from happening, even if it is predictable as ever. I crafted this guy because he is just that essential in Warlock decks right now, but it's a bittersweet feeling when you play him.. Feels like too easy of a win condition to pull off.

Unless it's against revive priest, fuck them.

I'm alright with win condition cards, as long as they are enjoyable to play against, or you have to put some work in to pull off.
C'Thun, the Shattered, Uther of the Ebon Blade, Mecha'thun are win conditions you have to structure decks and combos around in order to utilize well, all while fending off an opponents attacks.

Even less popular OTKs like Raza Priest and Waygate Mage took time to accomplish.

This.. Takes nothing.
With all the mana cheating options druid has been given, it's easy to slot this in anywhere, and pull off with little to no sacrifice.
Embiggen has a similar effect, but with a sacrifice tagged to it that balances out the boost in stats.
But worst of all, it's a win condition that doesn't end the game with a bang like we've seen with others.
Instead, the match turns into an sluggish and frustrating onslaught as you get overwhelmed by big numbers and value.
Just a hopeless, uphill battle you're forced to concede to.
And I'd rather get blown up by 20 fireballs in a flashy combo than fight a hopeless battle, that feels unfair and unearned.

 - Poorly designed card that is too perfect for the class it's been made for
 - Adds no enjoyment to the match
 - Easy to pull off with a massive reward
 - No sacrifice and no reason to exclude this card from your deck

1/5 Stars, haha big minion go brrr

Admittedly, I do really like this card and have it in my warlock deck; but it is too impactful and unhealthy for the game.
I feel as though it should cost 8 mana so it is more difficult to corrupt, should have 10/10 stats so it can be more tempting to play un-corrupted, and should maybe burn 3 cards max.

Removing such a huge portion of cards from an opponents deck for 6 mana, with a big body on top.. Maybe a bit much.
Especially with our favourite free value god, Y'Shaarj, the Defiler.
Fun to play.. But not enjoyable to play against.
Definitely a problem as it stands now.
