Fool's Bane, fatigue itself (if it does counter it), freeze mage, warlock THE CLASS ITSELF, so many other cards. This card is extremely powerful, and it has a half decent stat line. 3/4 would have been even better though.
This card is Not good in Warrior. Control/C'thun Warrior have enough problems trying to fit in 30 cards in the deck. This will take up an important card slot and doesn't have synergy. This card is so weak and easy to remove. Against aggro, would you rather play this over disciple of cthn, ravaging ghoul or frothing? Against control, this have such a weak body that takes up a card slot for a chance to take 1 fatigue damage? it still needs to survive a turn to take the fatigue damage. If you have this minion on board and your opponent can't remove it, you're already winning the match, the fatigue damage is not a factor.
