Sometimes characters have a certain something that's difficult to define in terms of direct description. Perhaps they're lucky, or doing things the dangerous way always pays off for them. These characters have Meta Traits.
Meta Traits are selected for a character like any other Trait during Character Creation or Advancement, but they use slightly different rules, and can be used in special ways. They might be less reliable, or have diminishing returns, or have a chance of backfiring, or some other restriction.
Some people are just lucky. They get through things not due to skill or natural ability, but because the winds of fate are at their backs. Of course, relying on luck can also backfire impressively. You can pull Luck for any check in addition to any other Trait. On any given Lucky check, if your Quirks (generally dice results of 1) outnumber your Effort (generally any dice result of 5 or above), you fail the check in some impressive or spectacular way, and you get to describe how your luck has turned against you. If it's your Turn in Combat, your turn is over, and you lose all remaining actions in addition to any other side effects.
You can also Burn Lucky to provide Synergy to any other player’s check; this doesn’t cause the Quirk related failure indicated above. You can’t use Lucky to claim Synergy otherwise.
It happens all the time in the movies — that crazy character that runs charging into a hail of bullets, but comes out unscathed. A great example of this is Wyatt Erp in the movie Tombstone (and, at least according to legend, in real life). In one scene, he walks out into a lake, completely surrounded, and guns down all his attackers without taking a single hit.
The Daredevil trait can be pulled or burned to be added to any check where you deliberately put yourself into potentially deadly danger; if you're playing it safe in any way, you can’t pull the trait, so no nets under the tightrope or firing from cover if you want to use Daredevil.
To quote TV Tropes:
A Genre Savvy character doesn't necessarily know they're in a story, but they do know of stories like their own and what worked in them and what didn't. They may attempt to apply the lessons they've learned from movies, books, or other fiction to their own situation, or they may restrict themselves to snarky asides and observations.
You can use Genre Savvy whenever being genre savvy would be helpful, but you have to describe the trope (or what have you) that you're referencing. It otherwise operates like a normal trait. I'd recommend having TV Tropes open in a nearby device, but try not to fall down a rabbit hole.
