Having tested:
Storm Tempest and Sludge Slurper,
Cable Rat,
Bogstrok Clacker,
Stormstrike,
2 Hoard Pillager and various numbers of Mutate, Wandmaker, and Faceless
This feels like the version I want to be on the most– but Serpentshrine is untested atm. It is hopefully just a replacement upgrade over Stormstrike that actually leaves you with a guy, combos with Mutate slightly better, and goes face in the same way while having an Overload on an irrelevant turn cycle. Once you cut Inara it seems like you want Portal > Stormstrike.
