Metallic luster is a shiny, reflective appearance exhibited by metals and some minerals. It is characterized by a high degree of reflectivity and a mirror-like surface. This luster is a result of the way light interacts with the free electrons in the metal's atomic structure, causing it to reflect light in a unique way that gives it a metallic sheen. Metals like gold, silver, and copper are well-known for their metallic luster. **

The effect of Black Luster Soldier - Sacred Soldier allows you to target one of your banished monsters and one card on the field, then return the banished monster to the graveyard and banish the targeted card. Additionally, if this card is sent from the field to the graveyard, you can add one Level 7 or higher Warrior or Spellcaster monster from your deck to your hand.

Metallic luster is the shiny, reflective appearance of metals and some minerals. It is caused by the way light interacts with the electrons in the metal's atomic structure. When light hits a metal surface, the free electrons in the metal absorb and then re-emit the light, creating a smooth, mirror-like reflection. This unique interaction with light gives metals their characteristic luster, distinguishing them from non-metallic minerals which have a dull or glassy appearance.
