This shirt. Apparently it was released March of this year alongside the Hoenn starters and I completely overlooked it. I found it online but the website is sold out of all sizes and so far it's the only place I've seen it listed. If anyone has it for sale or has seen it for sale please let me know as I'm not sure if there's any plans of restock (heck, I don't even know how long they've been sold out).
Secondly I'm not sure if it went unnoticed but there has been a new metal collection set released and it includes Noibat.
Thanks so much! :D
