At first, I also thought that it would be an incredible card. However, then I remembered Frostwolf Warlord. This card doesn't stand up in comparison to it. They have the same mana cost, but if you have 5 creatures on the board, say 3 of them are beasts, King of Beasts is only a 5/6 taunt when Frostwolf Warlord is a 9/9. Even assuming that all 5 creatures are beasts, King of Beasts becomes a 7/6 taunt and Frostwolf Warlord is a 9/9. Therefore, I don't think this card should be run. ;)
