Aggro rules the meta! I have hit fucking rank 5 by doing nothing but playing the mid range hunter in an aggro style. I can't believe it to be honest. I did it very quickly too. 19 to 5 in about 8 hours of play time spread over 4 days. With all the quests out there its insane to me that I have made it so far up the ladder with this shit meme mid range hunter. I drop Alley Cat turn one, opponent plays something in response 95% of the time, turn 2 I put down Scavenging Hyena, throw the Alley Cats into the enemy minion, and end up with a 4/3 that damn near wins me the game most of the time. The opponent has to waste resources/time getting rid of it which allows me to build a board which I can then adapt (almost always turn a 1/1 into a poisonous minion which I trade into large taunts/minions) and they can't keep up most of the time once the hero power comes in. Make sure you have deadly shots in the deck and you should be good.
Between double kill command and unleash the hounds (especially with a Leokk from animal companion on board), the rogues have a difficult time stabilizing as I can do 10-20+ damage in one turn while they are trying to bounce back minions. I can kill them on turn 6 before they get a chance to take advantage of the quest after playing it on turn 5. Obviously draw RNG is heavily involved but even still.
This is the highest I have ever been on ladder and while its cool it also sucks that control is too shitty to play. I know I won't hit legend but rank 5 is enough for me. Its frustrating that only like 4 decks work above rank 10. The one deck that is faster than the mid range hunter/murloc paladin is still that damn pirate warrior. I still get destroyed by pirate warriors with a good opening hand.
