Sandscape: Comments

I have written some of my own rules for ante. They are duplicated below for reference:

Ignore "Remove [this card] from your deck before playing if you're not playing for ante." The ante zone always exists, although if you are not "playing for ante", it will initially be empty.

Ignore rule 407.2 (about ownership changes) during subgames, and ignore rules 407.3 (about ante cards) and 800.4m (about cards remaining in ante when a player leaves the game) at all times. (The card may physically remain in the place on the floor used to represent the ante zone if ownership changes persist (see below about persistence of ownership changes), but the game cannot see that object; as far as the game is concerned, that object does not exist.)

The ante zone is shared across subgames. Objects in the main game's ante zone exist in the subgame's ante zone too, and when the subgame ends, those objects remain in the main game's ante zone. However, if a player is eliminated from the subgame and there are more players remaining, then the objects that player owns are inaccessible until the subgame ends (if something counts the number of objects in the ante zone, it won't see objects owned by players not in the game).

What happens to ownership changes once the main game ends (and how to decide the owner in the case of a team game, if applicable) is beyond the scope of the game rules. The "default" is for all game effects (including ownership changes) to end once the main game ends, and for this to not affect the scoring at all, although match rules may specify that they are used for scoring, that it lasts for further duels in a match, etc.

(The rules about subgames was actually based on an interpretation used in a puzzle, which I find interesting, so I decided to use it too.)
