Elder Sign
Can the base game's Yog-Sothoth be used with Gates of Arkham, and what happens to a gate when his effect removes an Other World card?
One reply gives this reading; it is unconfirmed beyond that thread.

Yes. Base and Unseen Forces Ancient Ones can be used in Arkham, though some are harder. If his effect removes an Other World card, its gate is removed from the matching Arkham card too.
