I assume this was originally played with normal decks, but the screenshots show special decks with only suits.

Doesn't this make a difference to gameplay? With normal suits, if you trade a few times, you may be able to establish that twelve distinct cards are in a suit even though you never saw more than say four of them at once

Maybe there typically isn't enough trading for this to make a difference? If there is, it does introduce an extra skill to the game of remembering the cards that have been seen before. That's valuable in lots of card games including some poker variants, but it doesn't seem like something JS would emphasize training.

If you have 12 identical decks you can turn them into 13 Figgie decks by combining all the cards of each value.
