This is the only 4 mana weapon with these stats in the whole game

Not only is the effect of the weapon OP, as every time warlock discards something, something bad happens, but the weapon also has the best stats for its cost. I've looked at all the other weapons from all classes and there's no other one with 4 mana 4 3, even though their effects are weaker than this one. Nerf this stupid card.
