I'd undo this. I'm not a fan of crest ranger myself, Her close skill doesn't let you gain sp, it's basically like being forced to let a unit die off without triggering an SS. In the beginning of the game this is actually a bad thing, and I think that if you want to use her you don't need more than 1 copy. Halbert however is a decent ranged unit that does attack based damage on close, he's isn't very special but he's pretty reliable.
Gon is right about using an undead around the start. However revenant isn't really that great compared to the other undeads (hell smoke is a lot better), but until you have better opening units like other undeads, EX langbart or some doll with doll master sumer to buff her, it might be better to use him regardless.
