I see a problem with Ghed. A person uses Whirlwind Ring,or any other method of pushing him back and the additional ATK and AC then are nullified, because if you fix rank with Ghen he is spent, if you use another card to fix rank he will be unable to attack.
Only a problem if you react. He has killer synergy with Xaros the Mist though. Xaros moves him, he makes it easier for Xaros' react. Slick.
