so some time ago I wanted to battle a friend in sv vgc reg f and realised that there is only reg c d g and I in the teambuilder validation place and in the challange a friend format selection place. I understand if it gets removed from the battle a random person place, but I'm pretty sure the formats that cant be found there you can still make teams for and battle your frends in the format.
TLDR; why is vgc reg f removed and if it is still there where can one find it
Edit: do say if the question is unclear, I can sometimes be very bad at explaining
