I think Frosmoth should go up for reservation(I forgto and already requested it, but it's not there lol.) Already is in VR, as of recently. Uncommon, but more of them than some other ranked stuff even, imo Frosmoth has the potential to go big by hard walling Iron Bundle(bar weird fire tera or whatever,) really hurting Flutter unless it's Mystical Fire AND you can't tera, and just generally beating the BM beast. I already made my case in VR, and it seems to have been accepted, but those are the highlights imo. Definitely seems to affect the meta some, and certainly what they bring.
Edit: this is for f I guess, when that's up. Not that frosmoth is a new return, but I wouldn't be doing an analysis, if I get to, for an outdated reg.
