Everything between now and the next game is just killing time
- When at the start of the Game Citizen Dawn is played and the Citizen Truth will Damage be deald? In the beginning before the play has started?
Yes. Always follow the instructions on the card.
- With Channel the Eclipse and Return with the Dawn when new Citizen are played will they deal Damage in the same End Villain Turn as they are played?
Again Yes, always follow the instructions on the card. Any card played will trigger during the turn it is played, if it has a trigger that has not happened yet; an example from a hero deck is Fanatic's Embolden (if played on herself).
