FGO JP: Advance Quest - Captain Scathach's Special Instructions, 3-Man Team ft. Cu Caster

The opponent has Special Defense Up against Normal Attacks, and your party has the buff when you attack Summer Scathach with the correct Card (example she activates Arts Damage Up?, you attack her with Arts), it will give you NP Strength Up buff.
She has 3 Times Guts (revives with 100k HP), so defeat her by depleting the HP and Guts status to win.
Always use Normal Attacks on the first 3 Turns for the NP Strength Up buff, then Scathach will cast NP Strength Damage resistance down on her 3rd NP Bar (aka. the 4th Turn), and use your NP to damage her. After her NP finished, the resist down ends and repeat the process.
Servants, Skills and Craft Essence used:
Scathach-Skadi (8/8/10) - Kaleidoscope
Cu Caster (10/5/10) - Black Grail
Merlin (10/6/10) - Bond CE (Increases Buster card effectiveness by 15 percent.)
Mystic Code used: Fragments of 2004

And I almost forgot when you use Waver on this battle: never use his NP, otherwise it will ruin the 4-Turn cycle of this Advanced Quest. Use only his buffs when needed.
Edit: And also the Skills with NP Charge drain.

Tried this solo using Cu Caster, but Summer Scathach's NP can Instant Kill any Servants if not careful, so I abandoned that idea.
