None of those legendaries are relevant in the current meta except for 3x Albert in neutral/midrange sword and 1x moon al-mi'raj in storm haven which are both tier one decks right now.
Eachtar dominated the meta in midrange shadow last expansion as a tier 0 deck but is a tier 3 deck now and 3x nepthys is featured in another archetype built around her fanfare that was also strong last expansion but irrelevant now .
Fairy Princess and fairy dragon are ran in some forest control decks which is a tier 3 deck right now and aurelia is a great card but used in control sword and control is irrelevant due to ramp and aegis being dominant.
Enstatued Seraph is a win condition card for seraph haven but outclassed by heavenly aegis at the moment.
The rest, Sea Queen, Eidolon, Flute and Imperial Dragoon are meme cards and see little play.
I would reroll if I were you.
Alternatively you could dust everything to build a deck of your choice but thats absolutely not recommended because you would lose out a lot if the meta shifts.
