I don't normally post my clears but I've been doing full Marisa team clears for a while, and this one has been the closest to me thinking it was impossible without swapping a Marisa out so I was quite proud of it enough to post.
I normally use Rearmed L'Arachel for these instead of a more Jehanna-themed pick (not that I have most of them modernized) because Flash support does wonders but I genuinely don't know if I could have done it with a fourth physical unit, and at least I don't want to push even harder on this map. I'm glad I've almost always been able to keep my fourth slot to Sacred Stones at least, to support my favourite game and favourite character.
I'm not sure how much this will hold up to future Celestials but I think it will be okay at least a bit longer.
Side comment, I thought I turned on enemy range and then accidentally turned it off but I guess I forgot for the first two turns even though I was supposed to turn it on earlier. Not a big deal but sorry to whoever that may somehow bother lol.
