I used some Adventure Variant expansion before, but I've never combined them with other card expansions. In Crown of the Elder Kings and The Scepter of Kyros the manual says that everytime an event from the base deck is drawn it must be replaced by a card from the expansion deck.
If I combine one of those Adventure Variants with other cards expansions (i.e. The Dark Forest), how should I treat the events from these expansion? Do I have to resolve them normally or they must to be replaced like the others?
