Definitely the "7 planets" are part of Evrart de Conty's 16 gods. And in the Mantegna Tarocchi. And at many other places.
We've "Trionfi decks" as the origin of Tarot. We've the expression appearing at the same time (1440) with the popularity of the Trionfi of Petrarca. We've Petrarca motifs inside the Trionfi/Tarot motifs. We've - likely - a lot of modifications in the long run between "first Trionfi deck" and "First Tarochi deck".
We've also a "rather empty time" between 1370 and 1440, which might have been filled with lots of playing card experiments. In the Michelino deck we've an example, how different the decks might have been.
That's complex enough. We have no need for the hardly proven elephant of "goose game" inside our Trionfi porcelain shop ... :-)
