You have many, many ways to counter her very easily, she might seem to be scary at first sight, but she really isn't.
The Mono Junta deck is strong, but suffers heavily from not being that stable (Stop opp. ability murders them, as well as -X Opp. Damage), and that you have to rely on tricky moves to be able to punch your adversary. While other clans (Montana/Uppers/Sakhrom ...) don't have to necessarily go all-in to succeed.
It's time for La Junta to shine a little bit, that would be a shame not to let them do so.
