There are a lot of bad Hearthstone cards out there. Every expansion has its dud legendaries and pack filler commons. Bad cards are just a fact of life for collectible card games. After all, we couldnt have good cards without bad cards.
But one card that Blizzard just revealed is worse than all these bad cards put together. Not only is it a bad card to play with, its also a bad card for the health of the game. In fact, its barely even a card at all. Its just a sneaky way for Blizzard to make more money on their next expansion.
