Hearthpwn

If I am not mistaken, this will give you a lackey on rogue and two imps on the board for warlock? If so, this card is really interesting on warlock...

I already suggested a solution.

They should think in new game modes that gives the game the twist it needs. The tournament mode was excited, as i said, but there might be others. A multi co-op game mode, perhaps? New arena modes based on the build-your-deck adventures? A "custom" ladder playstyle in which you can only play with two-three expansions that were released that year and every month they change it? It would be great to play with, for example, only basic cards and Naxx+Frozen Throne, or something similar. Or themed ladder games in which every week a theme is banned, for example: random cards, elementals, draw-a-card...A story mode based on WoW for beginners where they can earn a card/pack? 

There are others for sure, others that I could not think of or my experience would not give me, to be honest. As you said, saying it is a problem will not solve anything. I am just asking for new game modes to the desginers, since that is their job. If not, they should ask its audience. A guy created DOTA based on Warcraft 3 (and many other were created based on W3 as well), and another created Autochess games based on DOTA (Moba games), and so on. But staying in a comfort zone based on expansions releases will not solve the problem that many players are leaving the game, rather if it is for a month or definitively, neither the fact that the game is mostly ladder and that's it.

So a new Hearthstone expansion will be released in less than two weeks or so. The excitement is reaching all their players and all streamers will come back again and the game will be popular again...but i have the feeling that this idea, which in the past worked really well, nowadays is fading out. 

The main problem with the game can be related with the metagame...or not? Let's see all the game modes that hearthstone offers:

- Ladder: Rather Standard/Wild, this is the core of the game. You play until you reach legend or until you give or bored up. 

- Arena: The idea is brilliant, but it can be expensive (150g every new one) and you must be really good in order to earn succulent rewards

- Brawls: Each week a new brawl is released. It is nice and fun, until you get the pack. Then you play it like two or three times (or not) and leave it.

- Adventures/Expansion GM: Since the last adventure (ONIK), every new expansion Blzz decide to release a thematic expansion game mode. Since K&C (and except TBP), this game mode is almost the same. And the reward you get once you finished it is a card back. 

What i am trying to say is that Blizzard will not make the game great again only with expansions. From all the four game modes, the most played (and by far) is ladder, and you do not have any other source of daily fun except that. And the reward in there became meaningless after 6 years. 

I was excited when they said that the tournament mode will be released, yet they stopped that project because...

But rather than that, no other new source of a new game mode was ever considered. And your players are always complaining about the metagame since its your only concern with the game. And with every new expansion, Blzz cover their flaws and the metagame problems (also the balance changes - not so frecuent)

I want to say it again: After 6 years, I want to see real changes, changes that make me feel that every spent hour will be as amazing as it was for the first time I started playing this game. Naxx added the adventures, and BRM the Tavern Brawls. Since then, new game modes weren't added. Every new expansion only changes the decks that are meant to be played, but not the gameplay, which is why people is leaving the game, imo. And trust me, with this new fresh air, the earnings will rise up too. So stop worrying about money and start worrying about actual HS state.

The fact that they reverted 2 buffs shows that they absolutely know what they are doing.
