Only just looked through the Chaos cards properly and saw this one:
Shrine to Nurgle
Support, 2 resources 1 loyalty:
Kingdom. Forced. After an opponent's unit is damaged during combat, corrupt that unit.
As you can assign where your damage goes you could essentially corrupt all of your opponents units with only a few hammers. 3 of them in your deck and you could get one out fairly early.
Havn't played against it yet, wondering what you're thoughts on it were. Seems very powerful to me.
Correct, having played against it, I can tell you it is a beast to play against....
Essentially it forces the opponent to let chaos attacks through early on, rather than end up with corrupted units galore....
