OG Nero and Nero Bride

So, I got a bit tipsy at the company happy hour and decided to roll on a banner that I hadn’t previously planned to roll on...one $80 quartz pack later, I am now sitting on Nero Bride and an NP5 (yes, you read that correctly) Nero Claudius. I’ve been laughing like an absolute madman, since the odds of that are catastrophically low (I’ll calculate them later) and I actually couldn’t care in the slightest about Nero (and where was this luck when I was actually trying to roll for Illya...)

With a 4 star at NP5, it almost feels like I have to include her in my lineup, but using her as the last man standing seems like a waste of her talents. I have pretty decent Arts servants, like Archer Artoria, Saber Lancelot, Jeanne, Waver, and Emiya Assassin. Also, what the hell do I do with Nero Bride? The plan had always been to run Archer Artoria/Saber Lancelot + Waver + Tamamo (don’t have her yet but will probably whale during Halloween); where does she fit in?

To rephrase and summarize my question: my thinking is that Nero Bride is neither a good enough damage dealer nor support to be a frontline servant on a Squirtoria\Saberlot + Waver + Tamamo team, but she’s a good fourth position unit in case my main damage dealer or one of my supports dies. Am I wrong?

Secondly, what would you do if you had one of the hardest-to-kill backline servants in Nero Claudius, but that servant was upgraded to do ST levels of damage via an AoE NP and you had an Ozy to boost her Imperial Privilege proc rate?
