So I know the answer to this one but are random scenario's intended to be restricted to level 3?
Strictly reading it playing a random scenario is playing 3C. That means the adventure level is 3. Which means you can only rebuild your deck afterwards with cards that are 3 or lower.
Obviously this isn't the intent but I don't see anything that contradicts it. Is there anything I'm missing in the RAW? Pretty sure the RAI is that the level is the last level you played before the random scenario.
Yeah, they fit naturally in the story where they are, but you can easily play them at any level.
