Spirit or Merrin?

I’m planning to use 2 of the tokens from the upcoming andor era journey guide on Merrin and cere to speed up the JKCK farm as they are still good units by themselves. Should I replace spirit with Merrin for my great mother’s team in GAC defense? I have spirit g12 and I would have Merrin relic 6. I am also wondering if cere is somewhat usable before I unlock malicos. If she isn’t I could use that token on baby cal instead for ls ufu for starkiller. I could use Merrin for the dathomir mission too.
