yes, you cant buy wards, only 4+regen on his unit and/or make him toughness 7, and/or use one of your "dispel-oriented arcane item platform" minor mages as shadow to switch positions. its not easy to kill such a character. but i see that you're right in that when fighting daemons, you knew you were in huge trouble. when fighting elves, you ask "is the guy a douche WAAC guy? or a TRULY competitive guy(=wants to win immensely, but wants to win by his choices, not single broken combo)? if the latter, you are not screwed, while with daemons it was sure.
