I'm going to go with good old fashioned, "extra luck". Never know when it's going to show up, but it would definitely improve your general disposition when things tend to go your way.
Yes, that's my pick. To be exact, I want "low-level telekinesis" aka mutant luck power like the superhero Domino. Just walking around being a casual badass, barely registering the danger I'm avoiding.
I think Stan Lee said that being lucky is the best superpower.
Yeah, she was a high point. I can't see a whole Domino film, but she's hilarious as a supporting superhero. It helped that the actor sold it well; so nonchallant in the most extreme situations.
Hers was definitely A-tier, though. She was more like a Teela Brown - the Universe simply was not going to allow anything bad to happen to her, unless it was ultimately for her own good.
