We tried 2 rounds tonight, me playing Chaos and my wife playing Dark Elf, and we only used base game cards. I lost both of them. The thing is: Dark Elf has annoying supports such as the one that can return a unit to owner's hand when it's being killed, another example like the one that forces me to return a unit with 1 hit point to my hand. Moreover, she used some annoying scouts to discard my cards and used Chill Wind to corrupt my unit and stood hers...
Man, I guess the base game cards for all 6 races should be balanced, isn't it? But why I feel like it's never gonna use Chaos to win Dark Elf? How should I play Chaos on earth?
.
. I think it's my personal reason that I didn't use Chaos properly. Let me try more tonight and I'll let you know.
