I would assume it comes to effect before, the card isn't mentioned in the errata. I base my assumption on the fact, that the opponent cannot reroll that die => card comes into effect before any rerolls are made, which happens in the modifying dice rolls part of the attack phase.

This is relevant because this means that the die cannot be rerolled if the opponent has a Gunner or Luke Skywalker (Crew) if the complete attack should fail, thus reducing his attack by one.

Probably not that strong against opponents who have a constant source of focus tokens or a comparable ability like Keyan Farlander but other than that quite nice.
