Collectible Card Game Headquarters

Hi guys,
does anybody know why gauntlet option, challenge mode does not work? it asks me to choose the challenge set # and then I have to choose a subchallenge but as soon as I elect the option, the game says I have lost the challenge, no matter which subchallenge I choose.

Second: does anybody know how to unlock Overlord Sliver (set # 3, challenge 8?)?

Thanks
Marco

Your deck is illegal, either because it does not follow the Type 1 restricted/banned list, or because it does not meet the challenge mode rules. If it is not working for ALL challenge modes, then probably you are breaking the banned/restricted list.

I'll check then.
Meanwhile thanks for helping me.
