I am aware that if a card plays a Duraction card multiple times, that card stays out in play with the Duration (e.g. Throne Room+Merchant Ship). What happens if an Emulator plays a Duration?
I own Empires, which has the card Overlord, whose wording does not reflect the errata. My family and I simply play the Overlord by its old wording, since we own no other Command cards, so we assumed it would play as it normally would when playing the errata'd version. If something referred to Overlord's types, we simply made sure to include Command.
But after looking back we realized, wait, there is something different. Overlord plays a card and leaves it in the Supply. What we had been doing was obeying the rules as if Overlord was the card. For instance, if I play Overlord as Archive, Overlord would stay out in play with the set aside cards; it was an Archive. What would I do with the new errata'd Overlord? If I play Overlord on an Archive in the Supply, do the set-aside cards go on the Archive in the Supply? Do I set them aside elsewhere?
And in general, when an emulated card refers to itself, what happens? I play Overlord+Mining Village, I choose to trash "it"; do I trash a Mining Village from the Supply, trash the Overlord, or trash nothing at all and get no +$2? The wiki pages are doing no good for me.
