I'm a multi so collect quite a few different groups but my favourite to collect is XLOV, especially Hyun (my bias). They are honestly so fun to collect and pretty easy to collect now I've found a couple reliable and trustworthy goms. I love that their cards are so fun!
I have the most Evan PCs, but I also have quite a lot of Han PCs because I used to collect him a lot before. I started collecting Keeho, and more recently, Natty and Chaewon.
Love collecting Skz bcs they are my ults and Skz doesn’t have a visual hole like frrrrr . I was really hard to choose a bias when I first started stanning them but now my bias is I.N ❤️
I kinda go through phases. I’ll get really into one of my ult groups, especially if they have a tour or comeback, and I focus on collecting them for a while and then switch to another one of my ult groups. So whatever out group collection I’m working on at that moment 😊 rn it’s NiziU
ateez and all(h)ours! i mainly collect my biases only unless i like some other cards or its from sets i like / js album inclusions, so i purposely buy wooyoung, jihwan, and masami
i love collecting stray kids ot8 for album cards. it can sometimes be stressful but overall it's the collection i work on the most and brings me the most happiness :)
