Gonna post with some pre-judgement notes because I don't wanna get to the end of the contest and have to tell people they missed stuff that was correctable. (I'll do this throughout the week as well).
Import (Action, $3)
Choose one: Exile a non-Victory card from the Supply; or exchange this for a card on your Exile mat.
This lets you get expensive Supply cards, but in delayed fashion. Of course, you can continue Exiling cards if you’ve got other ways to release them...
This doesn't work/is a technical DQ / this isn't what exchanging is - from the wiki:
To exchange a card is to return it to its pile (Supply or otherwise) and put another card in the discard pile in its place.
You'll want to probably revise.
This isn't my card, but as I'm also considering an Exile related card, can you clarify?
From the wiki quote, Exchange has two aspects:
• To exchange a card is to return it to its pile (Supply or otherwise)
I guess this depends in how you read this card. Does the exchanged card go to the Exile mat (since the target card is from there) or does it return to its pile? While the former is more natural language, other exchange cards do go back to their piles without specifying, so I think that is a valid way to read. If that is the case, this should be fine.
• put another card in the discard pile in its place.
The target card comes from the Exile mat. But technically, the clause above doesn't specify that the card you acquire comes from a pile (only that there has to be a card to acquire). Are you saying (for this week's challenge) that it has to?
Lastly, cards acquired from exchanging go to discard. Is this a requirement? Gained cards also go to discard, unless they don't.
