So, here's my opinion on each unit:

Lilith: Very good unit. Only problem is single-target BB. Has fast BB regen, and works well when creating Mono-Light.

Edea: Good stats and Poison on BB, but is also single target. Works as leader when creating Mono-Earth squad.

Lava: Good unit. Works as Mono-Fire leader, and has AoE BB.

Merith: Not bad as a free healer. I don't recommend replacing her with Zephu, but evolve Merith to her next form. Replace with Elimo if you're lucky to pull her.

Grafl: Will work is you don't have many Thunder units. Otherwise, there's a lot more, better units.

Also, a question: Who did you choose as your starter?
