Neither player can Special Summon two or more monsters simultaneously, effectively shutting down popular "pendulum" or "soul charge" style plays.
As a Quick Effect, you can tribute this card to Special Summon another LIGHT Dragon-Type Synchro monster from your Extra Deck in Defense Position, such as Azure-Eyes Silver Dragon , though that monster is destroyed at the end of the turn. Other Technical Meanings
