1) Do cards like the weakness stack and kick stack count as "in the card row"? Can I put them in someone else's hand?
2) If I have "Identity Crisis" + Captain Cold, do I flip my superhero up after Identity Crisis is beaten?
3) Do Weakness cards count as a card type in "Atlantis Attacks?"
1) No, all the stacks are not part of the Line-Up.
3) Weakness cards do not have a card type. Notice there are no words in the the space below the image where the card type would be found.
