This combo can summon Light and Darkness Dragonlord instead of Filia Regis, but I prefer Filia.

This combo can also play around Ash Blossom if they try to save it for Dragonmaid Hospitality.

If the opponent tries to Nibiru you while you have spheres in play you can let Nibiru resolve instead of negating with Sheou. Then use the Spheres when tributed effect to summon Dark End/Light End (whichever you didn't use in the combo) from deck and fusion summon another Sheou.
