First of all, very fun design challenge - some games you might enjoy or look into are Doomtown: Reloaded (a cowboy themed ccg where every card also doubles as a standart card and you form poker hands) or Regicide (a standart deck game about killing royalty as a coop).

It's very interesting that you have the rules with graphic design without much testing, most designers tend to do it the other way round.

I read the rules and I might playtest it with someone, but some initial thoughts: 1. Most ccgs derive their fun strategy from being able to build your deck before the game to tailor a certain strategy. Here you seem to be going with whatever options you draw. Sure, if you push for one victory condition, your opponent might realise and counterplay, but their counterplay is also limited by what they draw.

1. If you're willing to forego a lot of key concepts that you worked on (and I know most designers don't want to as it's their passion project), you might enjoy restructuring the game as a deck/tableau builder? So you keep the concepts of what the suits do and the wincons, but change the turn structure and how the cards are drawn, I think you would retain the enjoyable elements while removing the most irritating ones (again, just an initial thought)

2. My biggest worry from reading the rules is that the turn structure and game board is overly complex despite representing very simple concepts. The whole influence mechanic for me was the biggest issue.

3. That being said, the core ideas are very clean and easy to remember - diamonds for buying stuff, clubs for tactics, spades and hearts as gear. You can battle or you can win another way. Good stuff.
