It's not a suit+value marking, it's just a mark for eg marking the ace of spades in an otherwise clean deck.

It's definitely not obvious. I was looking at it for ages and still couldn't work it out. So if it works for you I don't think anyone else will notice.
Thanks, I'm glad it's not obvious. I know the bikes are about the busiest backs you can get so it's easy to hide a mark on them, but of course as soon as I'd made the mark I couldn't unsee it and it really jumps out to me now. I've practiced dealing with an the entire deck and stopping on the marked card and I can do it reliably, quickly and without having to squint at the cards.
I did try some more obvious marks too, like adding a bird.
One thing these marks do require is that you can see the whole face. But for the trick I was adding marks for that's fine.
Very subtle. I too was looking for a good while. It's like an extreme where's Wally. I would agree that you can get away with much bolder marks.
Personally I use the flower on the top right for the value, scratching off like a clock, and for the suit I put a mark along the line on the top edge. Both very easy to spot and read while handling when working, even in less then perfect light and another magician friend of mine spent a good while trying to spot the mark. I think he assumed they were to do with the birds or the biker.
Aye - I like to mark force cards, and tend to go for whiting out the central circle. It's not been noticed to date, and in a lot of effects reliant on forces, I don't think card markings are on people's radar to begin with.

If the spectator doesn't engage in the effect, then the only thing left is the method.
I can't find it. I think however you are making life difficult on yourself because there is such an easy foolproof way to mark cards, no codes to figure out and really easy to spot.
Here is the thing with marked cards. Doesn't matter how they are marked as long as you don't worry about it, nor will the spectator.
In any case if it works for you then you have done an excellent job. Well done.
