Do Super Luck and Razor Claw bring Night Slash to a 1/2 critical hit rate?

Question

Honchcrow's Super Luck, brings crit ratio to 1/8, then razor claw brings down to 1/4, then Night Slash for 1/2.

Answer 1

It's even better than that: ever since X/Y, the combination of Super Luck + Scope Lens is enough to bring all moves to a 50% critical rate, and for critical-boosted moves like Night Slash and Sky Attack, that improves to 100%. For in-game battles where affection mechanics apply, if the affection is maxed out, the 100% critical rate also applies to all moves.
