I like the game idea but I find it too complex for a porn game.
It's frustrating to lose a run because your Search revealed two non-Trinkets when you have nothing to Return. With 1 Mark slot you have to keep the first card you can to get out of this situation.
When you have to reset you have to start back from the beginning and can't collect trinkets or gems until you have gone trough the full deck again. The first cycle feels like a chore.
The pace feels too slow. I have played many rounds, enough to buy a second Mark. I can reliably get Gems and feel like I have made significant progress. I feel like I should have reached a lewd reward by now, but I am still far from winning a round.
Suggestion: use different decks control difficulty. The full 53 cards right away is too difficult for your average adult games player.
