MArcomage

Hi!
I havent played on marcomage for quite some time now...and well, unless its a bug - im wondering why i cant play some cards even if I have the resources?
Some cards i cant play:
Centaur champion
Urk the Conqueror
Centaur trainer

Let me guess: you tried to play these cards in AI challenges, right?

Oh, yeah..they cant be played there? How do i know which cards are allowed and not allowed in AI challenges?

You can't play any rares in AI challenges, other cards are available.

Oh, thanks for the quick answer!
