Reveal 1 Ritual Monster in your hand; add 1 Ritual Monster with the same Level but a different name from your Deck to your hand. You can banish this card from your GY and send 1 Ritual Spell from your hand to the GY; this effect becomes that card's effect that Ritual Summons a monster when the card is activated. You can only use each effect of "Stars Align across the Milky Way" once per turn.
