Heartstone 5 - 5 Polymorph

LOL, I was playing friendly heartstone games with the eldest boy last night. I was playing Paladin he was playing Mage. He polymorphed my Lord of Blah taunt card. I applied Blessing of Kings? +4/+4 He froze it, I was going to apply a second +4/+4 and make it a 9/9 Sheep. I took pity on him and just killed him with a 5/5 Sheep LOL
