Commandercool, I'm holding this Gabriel against you. Preemptively binding my Zaerogoo for five turns? I have no bind recovery and no heal orbs???
Fortunately he gave me four turns to chip his HP down, but he still landed his gravity and I had one turn of bind going into Uriel.

Naw man, that ain't my husbando. See how he's only moderately beautiful? I don't even know that guy.
It's a little disappointing we've never seen Guiding Archangel Gabriel as an enemy. I wonder what he would do. Probably lots of binds, his active is Miracle Of Ice after all.
I'm unsure how much a real enhance would be needed but I suspect Freyja would be the obvious optimal choice if you were to ever obtain her. I can personally ignore this somewhat because I make that setup Balanced and therefore can just use Medjedra. Cu Chu is not bad because that one TPA really gets amplified on Bastet mults, and 5 turns is just nice to have. Spica might be alright to try out, though.
Yeah I guess I don't know how much one is needed either, and yes I think Freyja would be best case scenario. But I don't have her. With double Verdandis my practical max burst tended to be in the <4 million range, which isn't really enough for a lot of stuff, but the extra Bastet damage might push it over the edge, I don't know.
I find myself not actually using Cu Chu very often, but that might be foolishness on my part. Because Verdandi has momentum problems and seems to rely on chipping more than bursting, at least in my experience, my response to a bunch of jammers or poison is usually to orbchange the board so that I don't miss out on a turn of damage. With only one Verdandi I can rely on panic boardchanges less easily, so I figured some insurance would be nice. I don't have anywhere near the math skill necessary to figure out how losing a prong but gaining an orb enhances works out damage-wise, but mostly she's there for the haste and lock resist. I'll at least give her a try once it's possible to skillmax her, but that may not be for a while and I'm certainly not willing to lose Woodpys.
How replacable do you think Susano is? He's great, obviously, and for somebody like me that time extend is a lifesaver, but even with just one Verdandi lead this team is pretty bulky so I wonder if swapping him out for GZL might not be better. Doing that means I lose a lot of the bulk that makes him less necessary though, so maybe not. I don't know, I can experiment. I even kind of like the idea of squeezing Griffin Rider in there somewhere even though he's kind of a sketchy choice.
