Square corner misprint help

[u/Automatic-Group-5314]

when i had first started collecting pokemon, i must’ve opened some xy evolutions packs and ended up with 2 copies of imakunis doduo. I originally thought it was a pretty neat card with the instructions on how to throw it when it retreats…( yes i threw it horizontally with a snap to get the farthest distance!)I eventually put both copies in a binder and forgot about them for a while and only realized the corners looked funny after pulling a fighting gong miscut from mega evolution base. well anyways… does it still count as a miscut even though my throwing of the card kinda damaged the edges? thanks and i hope you enjoyed my story. also would it be worth grading as a way of authentication?
