It's been a while since I've read this (I think I read it near the end of 2019 and got to chapter 11 or 12). Someone's comment made me remember this so I searched for it and just came back to see that all the chapters had vanished.
This was quite an interesting premise though. This manga is basically a love letter to 90's kids and, more specifically, 90's kids who played Magic the Gathering.
Edit: I now realize that I must have read this on a different aggregator site. That would explain why it was not in my Follows.
