Does Legendary Jujitsu Master still return an attacker to the top of the Deck if it is destroyed by battle?!
Legendary Jujitsu Master is destroyed by battle.
Yes. Its effect still triggers and returns the battling monster to the top of the Deck.
If Ally of Justice Catastor attacks a face-down Legendary Jujitsu Master, does Legendary Jujitsu Master still activate?!
Catastor attacks a face-down Legendary Jujitsu Master.
Yes. Catastor's effect does not apply to face-down monsters, so Legendary Jujitsu Master flips and can return the attacker to the top of the Deck.
