Optimal time to complete this WoF quest is between 2 and 3 days before the event end, that is after the x50 sale but before too late to complete the legendary duel chest quest. And if you have been using WoF enough in the past to get WoF cards to 5 stars you might not even need to use WoF for the event quest - you could get these dups from the event coffers.
