How did you get your MVP title, in the local raffle lottery?
The answer is to why I'm an MVP (and by implication in your question, that you're not) is because I understand these higher-level concepts in Hearthstone (and by implication of your statements, you don't understand them). I'm here to donate my time to help newer players understand these aspects of the game.
By the way, just to share some credentials, since you probably view me as just some random person. I've won the Managrind tournament twice, once as a Paladin and once as a Warlock. I was also their shoutcaster for their tournaments for a long time. I've been on two top 50 Blizzard lists, playing as a Priest and Shaman. I'm also up to almost 6k gold from my success in Arena (I like constructed and Arena, but prefer Arena). In essence, I've had quantifiable success as a player split amongst a wide array of classes in the game. I may not be the only player with these qualifications, and I'm certainly not the only player who has comparable qualifications than these, but I do promise you that I'm far more experienced, knowledgeable, and successful in the game than 99.99% of the population, who would not be able to come close to these qualifications. If you put me up to another experienced and high-level player like Kithros, I may not be able to say the the situation is the same in comparison than him, but I can promise you it's true to basically anyone you see on the forums.
There's no way to say something like this without sounding condescending, but the bottom line is, I understand the game better than you, and such simplistic concepts of "I need counter-spell to counter an ability" is a very elementary way of thinking of the game; and you're unlikely to be a high-end player without understanding that. The problem is that many players think of concepts in Hearthstone like they would think of it in MTG; but Hearthstone isn't MTG, it has a different set of rules and abilities available to you.
If counterplay didn't exist, then there would be one best deck out there, and no one would be able to beat it. This blatantly is not the case if you watch what decks are winning though; there are tons of decks that are winning. The problem is that counterplay DOES exist, but many newer players don't understand how counterplay works in Hearthstone. You can keep denying it if you want, but the end result is that you'll be stuck below a certain skill ceiling if you keep denying it exists.
As I've told people many times in this forum, and still stand by. Most players come to the forum not looking to improve their skill in the game; rather, they're just looking to complain about why they lost. In other words, they view themselves as perfect, so if they lost a game, it couldn't POSSIBLY be their own fault, it must be the fault of something else in the game (most likely the rules). But that's obviously not true; both players are subjected to an IDENTICAL set of rules, and while you may occasionally lose a game from bad RNG (it happens), if you're consistently losing, it's something your opponent is doing that YOU are not.
So a person can either figure out what they're doing wrong and fix it, but they won't be able to complain any more on the forums because they'll realize how well balanced the game is. OR, they can keep doing the same thing over and over, refuse to change anything, refuse to improve as a player, and then keep coming back to the forums complaining. It's a matter of which you want to be.
So to go back to your question, why am I an MVP? Because I 1) know far more than you, and 2) am willing to share this information even against the stream of whiners who attack me personally for doing it.
