Have a look at one of the 3 or 4 Luka’s from Noir 2018-19 on Ebay. You could pickup the signed rookie, or patch signed rookie. There’s also the ‘Reigning Nights’ signature and ‘Shadow Signature. I picked up this one for about $700 Aus.
That noir card is gorgeous! Can’t wait till I’m shopping for my lulu. Good luck with your search. Keep us up to date of what you come across and what’s you end up going with please.
