Mage is just an RNG fiesta with Yoggs box and reno. I've gone from thinking it was a fun deck to just being totally tilted by losing so many games to mage because of random skill-less turn 6 box bullshit.
A lot of people think they are favoured vs mage since mage does turn 6 box but in reality they are massively unfavoured because what mage should be doing is turn 6 discover two 6 mana minions. At that point if those minions have deathrattle the game is over. It masquerades as a control deck but really mage does a huge midrange push and it's there that it tends to win. If it doesn't win there then it casino boxes and probably wins anyway,
