First try with Artoria, Tamamo Caster and Jeanne, wasted one CS and didn't work.
So I didn't realize the recording wasn't on until midway through the battle so only half of the full 41 turns battle, but the strategy should be 1) HP and NP re-generation so Merlin over Tamamo Caster and 2) strong single target Art servant with some defense/healing so Artoria is the best choice. Nero Bride or BB would work nicely here too.
Just art chain all the way. Not even gonna bother Da Vinci until it's absolutely necessary (ie when she has ignore invincible activated) and just focus on the mobs. Careful with the HP max reduction so equip with Atlas Academy uniform for some clutch debuff removal, it really did save me this time. Another point, after she break her first HP bar, she will charge her NP to full and NP immediately so be prepare, or like me, reset the game XD
