In your card example, the theory that posits that you picked the cards intentionally is something that can be subjected to scientific scrutiny. We are allowed to ask where you came from, what caused you to form the intent, and then prove or disprove such claims.
No such inquiry is allowed with fine tuning, because it's designed to terminate the scientific probing. The designer is beyond understanding by definition. You say that fine tuning proponents are still "open" to figuring out why or what this intelligent designer is, but unless you can provide an example of a reputable physicist actually working on this, it's a false claim. If there is such a poor soul out there, they are working on a sisyphus task, hoping beyond hope to understand the supreme being that made the universe.
First we were supposed to believe that the earth was flat, because that's how God made it. Then when that was disproven, we were supposed to believe that it was round, but that it was made 6000 years ago, in 6 days. Then when that was disproven, we were supposed to believe that maybe it was older but it was the center of the universe. Then when that was disproven we were supposed to believe that maybe it revolved around the sun, but that God made us in his image. Then when that was disproven we are supposed to believe that evolution did happen, but only because God willed it by fine tuning the universe. With each new claim, religion moves the goal post further and further beyond the reach of contemporary science, but they are all designed to trap the mind within religious bounds, where once you get to God you are not allowed to ask any more questions. Look up Hegelian dialectics for a fascinating example of this. Fine tuning is but the latest example.
Here is one physicist explaining how to falsify one version of the multiverse theory: https://www.preposterousuniverse.com/blog/2014/06/30/why-the...
The reason why the behavior of people accepting the argument is important is because with an unfalsiable claim like fine tuning, if you're not patient enough to wait hundreds of years for physics to figure it out, one of the few things you're left with is appeal to authority. If you can trace the claim back to a bunch of religious quacks who otherwise never made meaningful contributions to science, you may decide that it's not worth your time. (I am obviously not talking about people who found evidence of fine tuning, but about people who then use that as evidence of a supposed intelligence).
