I got a small collection going, 7 more waiting to be shipped. Also managed to get two fairly rare ones from smaller chuubas I enjoy, one was a lottery, only 10 exist, the other was requested via DM for a merch set that had an unsigned postcard.
Unfortunate that some talents are unlikely to ever have hand-signed cards, like Sui for example. I really thought she would do it for 5th anniv but fat chance.
I kneel!
