Oh yes, please don't consider my previous message as the truth that should go for all...
I do think the cards, even if they don't have a serial, look awesome!
It's just that when I purchase a model, I'd rather pay 1$ less and not have a card. It feels like adding a cool card to the model justifies a high price tag whereas I at least just want the model.
Honestly I appreciate nice box art too, but if completely standardised boxes with a small sticker or something would be cheaper (looking at you Aeroclassics and Panda) then I'd prefer that too...
But I cannot deny the beauty of something like a Patriot model that comes with a superb box, a nice stand, a collectors card and a nice envelope either.
