Hearthpwn

even if you don't have the same deck it's still pure rng, even control decks have some 2-3 drops and the most aggressive decks 4-5 drops, so even if your opponent deck is way cheaper there is still a chance you don't get the effect, these cards will definitely decide games on a coinflip, which tends to be really frustrating

Tuskarr Jouster could hurt aggro a lot, gadgetzan jouster too, the other cards look bad, and again, R N G 

Not knowing it was possible just shows you know little about the game, and 9 armor after playing alextrasza (means at least turn 8)? you should have way more against a grim patron since they pretty much do no damage before that

Also  warsong double frothing and unstable ghoul, alextrasza and shield maidens is 6 minions, he gets 12(6*2) from the whirlwind, 10(5*2) from the ghoul explosion, 4(2+2*1) from the inner rage, 2 from the ghoul trade, 12+10+4+2+2+2=32 damage not 39

Not saying grim patron is not op because it obviously is to some extent, but you having such a low armor as a control warrior in end game and the wrong maths doesn't seem like a solid argument to me

yet more RNG cards
