Jia Xu is also changed. The "Behind the Curtain" ability: black tool cards are canceled instead of non-targetable. There doesn't seem to be any change for Zhu Rong, except having Meng Huo as a synergistic character. But if that counts as a change, then Zhang Fei and Zhou Tai and many others also count, don't they? Also Guan Yu and Lu Bu are changed because their health caps are different now.
There are systematic changes and changes on a one-by-one basis. Ruler's abilities are systematically removed. (This includes Cao Cao by the way) And flipping over becomes stacking / unstacking. (This includes Cai Wenji). Cannot be the target becomes cancel after you become the target.
Who was the guy who can either draw or pick cards from others every turn?
