When the order bonus of level 3 activates on a boss who has attached prior to the turn, the boss no longer is a demon when he previously was and he reverts to whatever he was before.

for some reason it says that "you already have an upgrade for this character in your deck" when I try to put Iron Mask and Azaram in the same deck. I tried it with just those two cards.

For the surprise card that costs 400 gold, are the displayed cards the only ones you can get? In other words do you have a 75% chance of not getting an uncommon and something better?

well thank you sir

Is there one somewhere?

What can you do with "core rune". I can't add it to any deck
