Coach Kim:
Turn 1: Dragon Cheer
Turn 2: Taunt
Turn 3 & Beyond: Alternate between Breaking Swipe and Coaching
Use heals when necessary, tera if you want, but it doesn't matter

Shayna the Croc:
Turns 1-3: Breaking Swipe until you can Tera
Crunch until it resets our stats once, then use Power Trip once kim coaches you and you use Bulk up once or Twice

Eric:
Just here for vibes
