If the hit-event is modified by replacement effects such that no damage is dealt by the active-attack to the attack-target, it is no longer a hit-event - the attack is not considered to have hit when the event occurs. Damage may still be dealt if the hit-event is modified, but it is not considered a hit-event if the active-attack is not the source of the damage that would be dealt to the attack-target.

Example: Feign Death has the text “The next time you would be dealt damage this turn, prevent it.” If the effect from Feign Death prevents all damage dealt by the active-attack, no damage is dealt, the hit-event does not occur, and the attack is not considered to have hit.
