2+ Level 4 monsters
If this card is Xyz Summoned: You can target 1 "tellarknight" and/or 1 "Constellar" card in your GY; add them to your hand. You can banish 1 "tellarknight" or 1 "Constellar" monster from your hand or Deck, and detach 1 material from this card; this effect becomes that banished monster's effect that activates when it is Normal Summoned. You can only use each effect of "Tellarknight Constellar Caduceus" once per turn.
