【FGO TA】 Ooku CQ 4T ft. Okita Alter
Tried similar thing with Merlin-Skadi-Skadi at first, got to last turn and it turned out damage is a problem there. Current script is better, but still very card-heavy:
1st turn: QQ or AQ
2nd turn: BA or BQ
3rd turn: B (though Bride with event CE can probably substitute it with 2 crits).
