I've been playing Eliza/Cerebella since she dropped. Have some impressions, if anyone wants to read it.
She's really fun to hit people with. I enjoy it. People keep getting hit in the face by Horace Dive, I don't think anyone knows it's a high yet, but I've been consistently putting on the pressure with Eliza/Cerecopter by doing like c.lk, c.mk, assist, Horace, dash, c.lk, c.mk, c.hp, Horace, c.lk, repeat. It's of course cause no one knows what to do, but it's fun while it lasts.
I feel like her defensive options are really lacking. srk and lvl 3 are her only invincible/armor moves really usable defensively, and srk seems really shitty (looking at the hitbox, haven't got around to trying it in a match, but it looks like IAD attacks will just beat it). Neither of her lvl 1's look like they have any invincibility, and they can't be DHC'd before comboing/being blocked, which is really weird, and I guess that disallows super jump, air dash, Nekhbet xx unjumpable Showstopper.
For normals, I've been paying a lot of attention to j.mk. That one really feels like a great move. Great range, can be IAD canceled into anything, but I like canceling into another j.mk. I can cancel into super off that I'm pretty sure, and if the opponent is low to the ground it's a guarenteed combo (landing either one or two j.mk's). When I hit someone crouching, it seems like it always hits at the lowest point, giving me more time to confirm. And even when it gets stuffed, I'm so far away that it doesn't feel like people can punish me that often. I don't like j.mp, even though it looks like I would (outranged by j.mk, and will miss grounded opponents where j.mk never will), and I can't find a good place to use j.hk. j.lk is great for crossing up and hitting someone when landing. j.hp is really fucking slow. On the ground, basically just c.lk into combo, or c.mk if they out of range.
As far as assists, I'm looking at c.mk, c.hk, Horace, Anubis, OraOraOra, and Osiris Spiral. I've mainly been using Ora, and it's really good to set up with (the best she has, probably). I want to experiment with the others at some point. Osiris seems like MAYBE it'll be a suitable replacement for Ora if I'm worried about meter (right now I really don't care about meter). Anubis seems like it could be really good if I can find the right setups, but Horace seems like he'll be better in general, and can help with more setups. c.mk seems like maybe it could be really good, akin to Filia's c.mk and Painwheel's c.mp. c.hk seems like it'll be better against projectile users, and I can also just set sail and follow the boat (gets me nothing off hit, so probably won't use it).
As far as assists for her, cerecopter is really fun (like it's fun for every character on the offense), but she feels like she would be greater served by a DP assist. That's really all so far, haven't noticed any other weak spots she can't cover herself.
