(read: the same build that also lets her melt faces with Komachi's Narrow Confines of Avici)...
Well, yeah, if you're using Komachi (or Suika, Gathering and Dissipating is about the same); the thing about Satori is it's highly dependent who you're using, and considering there's going to be 56 characters and you can only use about a fifth of them (and they're practically -all- really good, esp. after endless corridors bring some of the worse ones more up-to-speed) it can be hard to tell who's gonna be around. And, once you're in postgame and using lv5 skills instead of mostly lv1, Satori does start getting less useful with her lv0s; especially once Gambler is nerfed out so she isn't naturally getting a massive damage boost up on the natural skill users.
I guess on the upside she'll be able to take a hit after that. It's pretty bad for her that she's still only "pretty alright" for characters with massive formula skills though; most characters that can pierce mnd are even only doing it with passives, at this point. Her innate 25% lower damage formula and bad defenses/affinities really hold her back.
I say this with having been -using- Satori for an entire playthrough on my second go-around, if she didn't have Gambler's +90% for a damage advantage she would have done way less than even people like Meiling who don't have awesome base stats, and with her fragility it can be slightly tricky to get her in to copy people later; even outside of Gambler she's liable for getting one-shot in my experience. She's great with Avici and Dissipating but... once Gambler is nerfed you can just get more damage out of bringing in another dedicated attacker, and they'll probably be able to actually take a hit.
This is part of why I'm interested in goofy builds made for her Endless Corridor passive because it's hard to imagine her not being a highly meh character without it! With how much competition there is for party slots I'd probably leave her out even if I was fielding the whole Earth Spirits party; however, if you use all of them and are in postgame, it's possible to fix up Satori's base stats enough to make her non-glassy (not bulky, but able to solidly take some hits with her high hp) so I suppose it can work... if you're using Komachi tank or something.
But yeah, ATK-Satori can use stuff like Mountain Breaker (Potentially outdamages Avici/Gathering due to close formula and half DEF piercing, and on a great bulky attacker, so it's easy to copy) and Super Scope (over half as strong over again as avici because what is balance) and Last Judgment, and Byakuren has good backup moves as the nearly-always-out tank in many parties.
