Have a Kingdom with no Actions, then Obelisk as the Landmark
If Obelisk is the Landmark, i demand the chosen pile to be Ruins.
But the ruins will not be included unless there is a looter in the kingdom, and as far as I know there are no treasure-looters.
Tl;dr: Black market, Page, Peasant, Young Witch, Tournament, Gladiator/fortune (bane), Bishop, Hermit, Urchin, Marauder, Possession; Events: Inheritance, any other crazy event, preferably using debt, vp chips, or Adventures tokens; Landmarks: Mountain pass, Orchard
Also, a while ago I discovered how to maximize the number of different piles of cards in a kingdom:
Black Market, Page, Peasant, Young Witch, Tournament, Marauder, Urchin, Hermit, some prosperity card to use platinum/colony, and a potion cost to include potions, then two more random kingdom cards, that might be the bane, but most of the previously mentioned cards also work. Plus any events/landmarks. For some real rules fun, choose a split pile for the bane (probably gladiator/fortune, just for the debt), or throw in crown. Make sure to use shelters, the potion cost should be possession, and make sure the prosperity card hands out vp chips, solely for the posession confusion. Maybe bishop, because it cares about costs and will leave new players wondering how to count debt and potions.and because most of these are inheritable, add inheritance, which has extra special confusion if you inherit the bane card. No room here for villa, but that's fine, you could replace crown with it I suppose, which has even more fun if they inherit a villa...But back to the original kingdom, the second event should have either debt, vp chips, or adventures tokens. For landmarks, use orchard due to the sheer number of differing cards here, and Mountain pass to confuse them with the betting mechanic.
