Cards that are marked for suits

[Jimmy88]

So,
last year I was on here looking for guidance on the study of marked cards.
Everyone was incredibly helpful with there directions and opinions.
Quick update, all coming along brilliantly! And due to this thread I discovered Boris Wild, became a huge fan of his and I'm happy to say he is a very lovely man.
So thank you Theory 11 forum.
Soon, I am learning Mnemonica by Juan Tamariz and I can not wait!

My question,
while I was playing with a Noc deck, I realised they're marked, but for suit only..

I'm not sure what would be the benefit of a marked deck only marked for suit.
Yes, they tell you the suit but not the identity of the cards itself, just hearts, clubs etc etc.

So am I missing something?
Is there an effect? Or system or routines I am unaware of what just requires suit markings?

Thank you for reading and thank you in advance for any replies.

Have a great Christmas.

Pandrea has some effects for them on his youtube channel. Assume the standard NOCs are only marked for suit because that's really all you can do with the design without being obvious.

They’re great for cheating at spades....or hearts

Maybe for a version of out of this world and similar tricks...
