Section on Memorial cards

Seeing as Memorial cards no longer exist in the cash shop, do I remove that section entirely? I feel like that's too much information to just suddenly delete, but that certainly makes it outdated... I mean, I could change everything to past tense and add on a section about Hero cards, but still. I'm not sure what to do.

I think it's most preferred if you use {{Archived|section=y}}.

Ya, never delete information unless it was never right to begin with. Archives would be preferred.

Thank you, guys! ^^
