- Q: A "Stegocyber" that was Special Summoned by its own effect is face-up on my field. In this situation, can I activate "Celestial Observatory" by returning that "Stegocyber" to the bottom of the Deck?
- A: Since a "Stegocyber" that was Special Summoned by its own effect is banished when it leaves the field, it cannot be returned to the bottom of your Deck to activate "Celestial Observatory".[1][2]
