The gate tile tells us to create a realm deck. Then, at the end of each turn it tells to change the realm card IF THERE IS ONE REVEALED.
Did anyone found out how to reveal the first realm card? It seems that I went through the dream without seeing any of those cards.
We completed the dream, activating every script we could find, and ended up confused as of how and when the realms deck would come in to play. I belive we read the gate tile rule exactly as you did, Pierre. At the end of each turn, we would check if there was a realm card revealed, and when this was not the case, we continued not ever revealing any realm deck.
Indeed the gate tile states:
change the realm card IF THERE IS ONE REVEALED.
Perhaps something to be corrected in the script app somehow (if the script app is still being worked on?)?
