Blessing of Kings is 4 mana give a minion +4/+4. Are you saying that for just 1 extra mana, a card should give both taunt and divine shield? That would be op as hell
Pharaoh's Blessing is a perfectly balanced card. But I do agree that it could be better. I'd much prefer to pay 5 mana for it, if it gave a minion +3/+3 instead of +4/+4.
