Thanks to @Mayonnaisinator for these screenshots for the Item:Nullity's Mythic Cards (Level 160+).

Posting to confirm that the Item Card Variant code:0 is correct for this Item.

This is to avoid confusion or questions, because the Item:Nullity's Mythic Cards (Level 150+) has the Item Card Variant code:1. See details here.
