I'm not sure about this one. I mean if the opponent has many minions, it is still lots of incoming damage, against single targets we have similar thing just for 3 mana. Also the 3/7 body for 7 mana is pretty weak. I do not say it is bad, but definitely not OP. Probably best against handlock, but against it, paladin already had the tools.
Pretty strong I think. May even be played in some buff/token paladin deck using all the Eggs to buff their Attack to one (might be a waste, though :D)
Battlecry: Change all enemy minions' attack to 1.
all enemy minions'
Wow, either it didn't say "enemy" when I posted this, or I totally overlooked it.. I read the text several times to figure out whether or not it works on your own minions. Well, this only makes it better!
