The Medici changed their heraldic in May 1465 from 7 palle to 6 palle, one palle then including the French Lille.
Earlier there were other changes of the number ... they were reduced with the time.
The action was caused by French king Louis XI and his problems with Burgundy and not satisfied nobility, which lead to a war and the Battle of Montlhéry in the same year at 16th of July. The financial help of the Medici - which naturally accompanied the change in the heraldic - caused that a lot of Florentians found a new home in Lyon (new capital of France) and on long sight it caused two Medici princesses becoming Queens of France in 16th century.
Sforza was also engaged, who sent Galeazzo Maria with some military. http://fr.wikipedia.org/wiki/Bataille_de_Montlh%C3%A9ry
Nonetheless Louis needed some luck to survive the crisis.
According the Trionfi.com theories the Charles VI. deck was made ca. 1463, likely for Lorenzo's 14th birthday, 1.1.1463, still in the 7-palle time. When the France-Medici agreement was made in early May 1465, Lorenzo di Medici likely already had started a journey through various Italian cities, which should lead him finally to Milan, where the bride entourage to Naples for Ippolita Sforza gathered with some connected festivities, diplomatic talkings etc.. Lorenzo had to accompany the entourage till Florence, where the entourage intended to participate in the Giovanni festivities (24th of June).
The news about the 6-palle-change (and the connected political messages) reached Lorenzo likely during the journey.
According the Trionfi.com theories Lorenzo got the idea to present the 6 palle in 6 cards, which he intended to present to the Sforza (the six added cards in the Pierpont-Morgan-Bergamo Tarocchi). Possibly he used his stay in Ferrara for this activity (the stay took longer as expected, and Lorenzo's father, Pietro di Medici, wrote a demanding letter).
Well, somehow the 6 cards arrived in Milan ... with Sun + Moon + 2 cardinal virtues, which were in the Charles VI. but not in the 14 Bembo cards. And with a Star, which probably already had arrived in the Medici deck as a new card, when the Medici Chapel (with 3 holy kings, which presented sun-moon-star) was opened ca. 1464/65 and was celebrated with a triumphal march (a 6th of January 1465 seems logical).
And with a card with 2 putti carrying the picture of a city - identified as "World", but probably somehow indicating a French Lille in the new Medici shield.
But thanks for this picture:
For something like this I was looking for. And a picture from the Medici chapel (painted 1459-64 by Gozzoli) very precisely meets the spot.

Regulations for the Joust in Fifteenth-Century Europe: Francesco Sforza Visconti (1465) and John Tiptoft (1466)
This article examines the role of the Sforzas and Viscontis in Milan who set up 'Regulations for the Joust' to be staged at a wedding in 1465. For the first time the text of the only copy preserved in the State Archives of Milan is translated into English. The travels of John Tiptoft in Italy are traced from 1458 to 1461 followed by the text of his 'Ordinances' of 1466 (Ashmoleian Ms no 763 version). Both regulations are compared in detail focusing on the quantification of performance, targets, and actions. Despite striking similarities it can only be stated that the Italians preceded the English by one year.

This is an interesting detail, which I didn't know of. And it looks promising ...
