Actually the card is fine because it can attack straight away so you can either ping off a weak minion and get the attack raise to pressure your opponent and with 3 health it can trade or you can combine this with a whirlwind effect such as Blood razor to get a 2 mana deal 4 damage to a minion.
My complaint is not with the card but with something else I am confused about. Ahem... WHY REMOVE THE ENRAGE KEYWORD IF YOU ARE JUST GOING TO MAKE MORE ENRAGE CARDS!!!!!!! What the actual heck Blizzard?
The enrage keyword cuts down on unnecessary wording. Removing the keyword just adds more text to the cards. Now I would understand this if they were not going to make anymore enrage cards, but if they are still going to print more cards with the enrage mechanic than what was the actual point of removing the keyword?
Quick analysis base on current cards. The deck is Control Warrior
1. Play on curve turn 2: Can remove 1 health minion and turn too a 4/2 or 4/1 minions. Pretty good given that the infestation of Paladin on ladder right now and Hunter in the future. If there is no 1 health minion however I think you should just armor up instead.
2. Combo with any WW effect : The main use of the card. It can remove 5 health minion which ís good for 2 mana spend.
3. Combo with Cruel Taskmaster : Became 4 mana 2 cards 6 damage fireball to a minion and leave a 2/2 on board. Which is also good for the cost. I also love Crueltaskmaster he is so old school , and very versatile always jump in to ping off a minion, or buff armorsmith, AoP and now this card.
