have we had an international 13-0 yet?

since franchising started*

i dont think so

Internationally

before franchising:
Gambit 13-0 G2 (EU)
Gambit 13-0 Team Secret

but after franchising:
nope

no, gambit are the only ones to 13-0 ever. once against g2 in berlin master and once against secret in berlin champs 2021

well there it goes
