also, the Time Traveler expansion. Also looking for the graveyard and dragon hoard cards.
The Time Traveler can be found in Eminent Domain: Microcosm as a promo.
As for the Guild Leader it seems like it had only been in the KS and the others I don't think I've even heard of those before... But I could be forgetting.
Edit: Just remembered. The graveyard and dragon hoard cards were only in the KS as well. Only way I have seem to find those and the Guild Leader is to maybe find the KS edition on E bay.
