My thoughts.
Geome - odd name. Doesn't roll off the tongue well. Doesn't identify the theme at all. Did you have other choices?
Overall design, not bad. The worn out, scratchy look is fine for the faces, but it makes your back a one-way design and doesn't look nearly as good. If you wanted to get really sophisticated, you could conceal a subtle one-way mark in a non-scratched design, or even an entire deck marking system.
The courts - on the surface, the idea of the crowns is a good one, but there's something missing. If I took any of those courts and showed them to someone without indices, they'd have a hard time identifying them. Consider a more unified design scheme for each rank - crowns that are more similar without necessarily being identical. Make the Jack crowns flat on top, like they appear on a standard court face. Look at the Queens in a chess set - how does one immediately tell them apart from the Kings? Use design elements like those in the design of your Queen crowns and King crowns.
Don't use MPC if you can avoid it. Make Expert PCC or Legends PCC a stretch goal. And dump the IGG campaign for a KS campaign, unless geography prohibits you from using KS.
Also, be aware that we are running a design contest right now! Winner gets their deck produced by Expert PCC AND receives three gross of their deck (36 dozen, or 432 decks). There's a link to the contest rules in my signature, below!
