The card Now or Never says
Works as a Ghost card worth 4. At the end of the round, the one who played this card places it on their side of the 10th round and it will be worth -2.
It is clear how that works if the card is played during a normal round. But players can also pre-commit cards to round 10 - can this card be used like that? If so, is it effectively worth 4 (the -2 doesn't happen until "the end of the round", so it never happens), 2 (both the 4 and the -2 count), or -2 (the card effect implies that once it is on round 10 it is worth -2, so putting it there on purpose is self-defeating, but might theoretically still be useful as a bluff)?
