The cards for ARB and HPDR (the offical acronym for dream rap battle /nm) are going to be in separate tabs on the cards page. At the moment, Oran is working on the relationship pages but will make the other tab later, so be patient 🙏 He'll follow up with you later on specifics. I'm just leaving this so you know what's up. Thanks for asking!

Oh I didn't know there was an official acronym, I'll use that from now on! Thank you for the update, I don't mind waiting at all since you're focused on other things at the moment 🙇

Alright hi, here's the follow up. There are now sections on card pages specifically for HPDR, complete with sections for MC cards, Memory cards, and card cameos. For the duo memory cards, they would go under the main memory card section for the character they technically belong to, and under card cameos for the ones just featured. (For example, the Hifumi and Doppo memory card would go under Doppo's memory card section, but Hifumi's cameo section.) If there's any further confusion, let me know.
