Variant Request: Inverted Suit

[jakestiles]

Cards in the Inverted Suit play when discarded and discard when played.

Example gameplay
Example A: Alice clues Bob fuchsia (or whatever color gets assigned to this suit) touching one card. Bob discards it which causes it to successfully play as the Inverted 1.
Example B: Alice discards her chop which is unclued. It was the Inverted 4 so it plays unsuccessfully and generates a strike.
Example C: All 1s are on the stacks. Alice has an unknown 2 in her hands. She doesn't know whether she should play it to play it or discard it to play it.

Art
The art for these cards could perhaps be made by turning the number values (and/or the symbols) upside down and/or backwards.

Coding exception
A small extra coding exception has to be made for this suit. Normally you may not discard at 8 clues. But cards can be played at any time. Thus if a player plays an Inverted card at 8 clues, it should be discarded and should fail to generate a 9th clue.

Name and implementation
I'm fine with the suit being renamed. Maybe Silly or Opposite or Disobedient. Or just named after whatever color it gets assigned.
This might work better as a suit modifier (like Reversed) than a suit of its own (like Null).
