I saw a similar thread linked to in another site (can't recall where now), but inspired by Twitter I thought it might be fun to play this game.
We'd be hard-pressed to beat Tasha's Hideous Daughter that I saw there but how about these (apologies if any replicate what others have done elsewhere, genuinely what occurred to me):
Milf's Acid Arrow
Manic Missile
Fight
Protection from Eval (in case of motorbike stunt rider attack)
Vicious Cockery
Funbeam
Sleet
Hole Person (and the more powerful Chasm Person)
Power Word: Stud
Produce Blame
Barfskin
Speak with Planes
Lightning Belt
Remove Nurse
Eldritch Beast
Bong of Rest
Seeping
Defect Magic
Countersmell

I like Manic Missile, Fight!, and Countersmell.
