Robb Stark KOW reads: "Any Phase: Name a Trait. Until the end of the phase, each character you control that has that Trait gets +1 STR (+2 STR instead if it is Winter). Limit once per round."
What kind of effect is this, and how does it affect cards that come into play? Example:
I have Robb in play, along with Sansa Stark, a lady. I use Robb's ability, and choose "lady." Now Sansa will be +1 all phase. Later in the phase I put Catelyn Stark (KOW) into play. Catelyn is also a lady, but was not "controlled" by me at the time I triggered Robb.
Is Catelyn STR +1?
The real question is - does Robb's ability happen once, giving out its bonuses (which last until the end of the phase), or does the ability sort of globally apply all phase?
