If I’m reading correctly, Base Luck scales to way weaker than 50% Dark Disciples, and thus 31.44 Teratons. His True Magic scales straight to Dark Disciples/Leopold, making him 62.88 Teratons when using it.
Deku scales to being completely unaffected by attacks stronger than 33.44 Teratons, as Shigaraki had a massive evolution despite already being Prime All Might level and couldn’t even make Deku budge with a full on punch.
So base to base Deku can’t even be hurt, though he runs into problems with Lucks 6-B+ dura and then AP amp with True Magic. He gets around that, as well as Lucks speed amps, with Gearshift being able to also stack speed amps (2nd Gear sees base Luck as frozen, then 3rd Gear is faster, then Top Gear, then combined with Fa Jin creates Overdrive), Danger Sense alerting him to any of Luck‘s attacks, and Blackwhip restraining Luck’s limbs so he can’t really fight back.
After he gets Blackwhip/Blackchain on Luck, all he has to do is Overdrive spam and Luck should fold pretty bad. He won’t really get any time to adapt to Deku’s predictions or outspeed Danger Sense since Deku goes for instant KO’s as fast as possible.
