Well, it was you, that have been interested in cliffs.
yes, the bottom of the court cards in the Bembo cards signifies court cards, totally 12 cards, and the bottom repeats also on the chariot. So, it's not used without idea, it shows trump 2-7 in a sequence with the exception of card 6, love. At the end (7) the detail is raised, as it appears with the cliff at the end (card 21 or card 19th, second painter) of the row, the deciding detail is raised in the middle of the picture. In the 14 cards (first painter) the cliffs end in death, on the 13th, but heaven opens in the 14th, judgment.
At this picture the cliff or the island is used to signify birth, loneliness, singularity, individualism ... "everybody is born on an island", grabbing something, which is very deep in the soul

If you wish to see the Hofämterspiel ...

The cliff is on the 6 of the 14 Bembo cards
1-6-10-11-12-13
The Hofämterspiel-courts are at
1-6-9-10-11-12
The Hofämterspiel has only 12 courts
That this appears accidental, is against any probability calculation ...
...
6 out of 12 has 12x11x10x9x8x7 / 1x2x3x4x5x6, that's 11x3x4x7 : 1 , that's something like 1/914 ... as the other concept is a variation, on might increase the worth a little bit, but I would say the worth stays below 1:100
either there meet two features and the meeting is caused by a general custom (other playing card decks had simply a similar idea), or it is the result of communication between two individuals, for instance Galeazzo Maria and Ladislaus.
If we take 1-6-10-11-12-13 ... the special cards usually (if the decks weren't shortened) always had been Ace = 1, banner = 10 and 3 courts = 11-12-13, so the most of it is simply "common" ... if one assumes, that Fool = 11 and not 0 for some time (as a lot of people still believe, that the 5x14-idea is nonsense, this sort world doesn't exist for a lot of people).
Although this is common playing card behavior, nonetheless we have an unusual behavior about the "6" in both decks, otherwise more or less unknown. Six and sex and Jungfrauwe + Love ... that seems the special thing about it, and it is honored by an exceptional cliff at the one part (Love) and by a "Jungfraue" at the other.
Some time later - after the meeting of Galeazzo Maria and Ladislaus in 1452, the German Fool got the worth 1 in Bohemia in a rather unusual deck and the more famous Fool of the Tarot cards stood at the begin of the rows as a zero.
What shall two 12 and 8 years old boys do in the boring presence of many important adults ... they exchange about games. They show each other their toys and perceive the differences. Galeazzo was 8, Ladislaus 12. The elder mostly have some dominance.
The Sforza cards were probably made after the meeting in spring 1452, the informing letter about a card production in Cremona between Bianca Maria and Malatesta and Francesco is of November 1452, at least according the opinion of Andrea Vitali.
