This might venture into the #off-meta-fun realm due to trying to force Chun-Li or Shun into a comp possibly at the expense of a more effective unit but the goal is to use my LDs and I feel like there /might/ be something actually effective possible here.@wraith breach hoping for your advice on this since you seem to be the veteran Shun user.
I don't have a Water PVC, Chiwu, or Deborah so some of the classic cleave comps for my Chun-Li or Shun won't work. I feel like a mix of one of the following is the right direction for "next best possibility":
Gin (L) or Gemini (L) for SPD lead and strip. Maybe Tablo?
Kahli or Hraes or Eshir or Praline for buffs, extra single target clean-up damage
L Chun-Li or Sonia + Shun for cleave damage
+1 extra damage, buffer, or stripper (Shun, a 2nd Leah/Chun-Li, Tiana, Laima, Dark Robo, Galleon, Truffle, Gemini)
