The advanced search sometimes has difficulty finding cards in the system with more complicated names like Retro, Borderless & Extended Art variants. Because of this the Advanced Search will occasionally show a card as Out of Stock when we have it available but just in an alternative printing.

After searching for your cards try using the normal card search at the top of the page for cards that appear as "Out of Stock" in the advanced search - their alternative art variants will come up if they are in stock!
