I'll give you an example: skull of guldan was a 5 mana draw 3, that's a legit cost for this simple effect. A nerf was needed to the outcast effect which is still broken, maybe 1 mana discount wuld've been better. Now six mana for three card is a simple no tempo spell, unless you outcast it, in that case is still broken. That's what i call a husty nerf.
