Most decks of playing cards have three face-card ranks, though they may vary in exactly who is depicted: English decks have Jack / Queen / King, Spanish decks have Jack / Knight / King, Swiss decks have Under / Ober / König. But there are some with four: Tarot de Marseilles, for example, has Jack / Knight / Queen / King.
So I allow room for four face-card ranks in OneJoker Ordinals. Most of the time, this shouldn't be an issue, since the relative ranks are still the same (Jack < Queen < King). But be mindful of the gap when you are simulating a game like Poker or Gin that has rank sequences. A king-high straight, for example, has ranks 9-10-11-13-14.
