"Duration cards are not discarded in Clean-up if they have something left to do; they stay in play until the Clean-up of the last turn that they do something."
- A Duration card stays in play until the clean-up of a turn in which it has nothing left to do. So, if Blockade has nothing left to do, it goes away. This has been an issue with e.g. Cargo Ship, where stuff can happen after clean-up. Blockade isn't contributing new behavior here though. If there's no card on it, it has nothing left to do.
"Leave Band of Misfits in play until the Clean-up of the turn the card it played would have left play. Normally that means you'll discard it that turn, but if Band of Misfits plays a Duration card (Duration cards are in other expansions), it will stay out like the Duration card would have, and if Band of Misfits plays a card like Throne Room that plays a Duration card twice, it will stay out in the same way the Throne Room would have."
- A card that plays a Duration card without putting it into play stays in play as long as the Duration card would have. Conjurer normally stays in play until your next turn. It's kind of nonsensical to talk about whether or not a Conjurer not in play "would" stay in play. If you Band of Misfits a Fishing Village, it's not in play, so it wouldn't stay in play; except, we all know, it would stay in play if you played it normally, and that's what the Band of Misfits rule is talking about. Conjurer is unusual here in that what it does next turn involves the Conjurer card itself. If it's not in play it can't do that; if you old-Procession a Conjurer, it won't have anything left to do, and so wouldn't stay in play, even though this is because it's not in play and so no-one would ever ask that and it's a weird nonsensical question. Anyway it's the same here; Conjurer wouldn't actually stay in play, since its conditions fails, confusingly due to it not being in play. So Band of Misfits shouldn't stay in play.
