I haven't read the past 190ish pages, but my question isn't asked in the wiki.
Last month I started a 5 person circle, all different bank accounts, ssns, address etc. but I used the exact same card for them: my UA Club
I didn't have a problem this time transferring 5k total (split up with random values) but am wondering if there's anyone who has experience doing this themselves, and if it's working out.

If I can continue doing this, I'll keep the card; otherwise I'll cancel it.
