The end of an Era has come. Magic is broken. New Heroes are needed to face the challenges of the new Age!
I will vote for lucky streak at first and the removal of the bad luck spells.
If we don't want to use Moment of Prescience for 8th, as it might be more appropriate for the Oracle/Prophecy domain, there is a spell called Mantle of Egregious Might that gives you a +4 luck bonus to attacks, saves and some abilities.
That spell is from Sword and Sorcery, not official Wizards. If we start going into those spells, we are gonna be forever doing this.
