If you dont have CRs or Futoshi, dont play FPC, play La Junta

You can play without Marlysa or Kerozinn, but use a half deck. Heitachi/Yoshida/Kuei, Shifou, Zhu Tang/Ralph, Kusuri.

FPC isn't really meant for mono, if you want to play Mono for +2 damage definitely go for La Junta instead.

Some cards I'd take for half (You can mix-and-match to get the combo you like):

2* Kusuri and Chan
3* Shifou, Zhu Tang, and (debatably) Ralph. And Nakata, but I don't like him.
4* Fei, Heitachi, Futoshi Ld. To me they're like rock-paper-scissors, each having their own pros and cons against specific opponents. As a result, I like to run at least two out of these three in Elo.
5* Kerozinn Cr, but you don't have her. Try Yoshida, Tsubame or Kuei instead.

Totally agree with Amberred1994.

La Junta can make a good 5-4-4-3-3-2-2-2. With junta, you should either go odd damages or even damages.

For odd:

Naginata, Sabia, Wyre, Tolliver, Bryan, Thormund, Brianna, Trish

For even:

Isatis, Milena, Ray/Raven/Pilzken, Jane Ramba Cr, Chiro, Wardog, Victoria, Dean

The reason for this is 2hkos. La Junta can often just win 2 rounds and win the game. Good luck.
