If you control a "Constellar" monster other than "Constellar Caduceus": You can Special Summon this card from your hand. During your Main Phase: You can add 1 "Constellar" Spell/Trap from your Deck to your hand. You can only use each of the preceding effects of "Constellar Caduceus" once per turn. A "Constellar" Xyz Monster that has this card as material gains this effect.
● Before damage calculation, if this card battles a LIGHT or DARK monster: You can banish that monster.
