At this point, depending on how the bard buffs, they would at most probably try to change the cards to match the effect of the songs even if it's only surface changes, just adjusted values since they're only single target while Divination stays the same. Probably solar cards would be the damage up buff, lunar, direct hit and celestial would be crit or anything like that.

That being said, while the personal dps feels a bit better with some use getting use to the new minor arcana change, the new noct change doesn't feel noticeable.
