First as far as nerfing Miracle rogues I disagree completely with that junction. The problem isnt in the cards, the problem is to many people get on this game after they have went on google or a twitch stream and watched some high level player beat face with random dot deck and expect to do the same thing without any research or practice with or against the deck. If you want to move up the ranks and be a better player id advise you take the time to go through the cards and experiment on your own in casual mode until you have figured out a game plan or a deck to fight against miracle rogue decks or the top deck at the time.
Now for the miracle rogue players such as myself. If your having problems with Zoo type decks you simply have to do what I said in the paragraph above and stop copying the decklist some legendary player won with a week ago. For example right now I do not play Blade Furry in my miracle rogue deck or the 3/3 guy that gives you +3 life (cant remember his name) I replaced them both with Kobold Geomancer. Kobold Geomancer with Mainly Fan of Knives but any spell that does damage will win you 90% of your Zoo matchups. The key to beating zoo is to keep there board clear from the start, the first 3 turns are the most important. So learn to mulligan when against a zoo player. Mulligans are by far one of the most important parts of the game.
Now to beat the miracle rogue leeroy shenanigans. High level players already know this and do it very well. "TAUNT" my god a simple mechanic called taunt is the miracle rogue hate all day. People still argue its not because they got double sapped...sometimes you just have all the answers to win a game and thats part of any game ever made so learn to understand it. Ive been brickwalled and stop dead in my tracks because the person playing against me knew how and when to use TAUNT against me.
All in all this goes back to doing your own research and play testing and less whining and criticism. The answers are always right under your noses, you just have to look adnd adapt. Nerfs are not the answer for your inability to act and think like a top tier player.
Also everyone is wondering who the hell am I to put all this out there like im some Hearthstone pro. So ill tell you I got the beta invite when the game came out and since I play alot of Magic the Gathering which im very decent at, I dismissed this game as a poor wannabe ripoff of it. A friend of mine always taunted me about how he would smash me in this game. So 2 days ago I bought 80 packs because I work and can. I built the miracle rogue stock list off the internet and went right into casual mode al day the first day switching cards in and out and then once I settled on my list I played for 4 hours on day 2 which is today. Went from rank 25 to 14 losing a game to my misplays every 4-5 games 99% of the time. This game is very easy to me because of the 10+ years of magic the gathering ive played. So keep looking for new ways to break the meta game and conduct lots of practice. Ill see you guys in legendary ranks real soon! Thanks for reading!
If you want to learn a ton more im always willing to talk one on one, just let me know. I have way more to add to this but for now this is it!
