Rulings
- If Legendary Jujitsu Master is changed to a Fiend or a Zombie by DNA Surgery and is attacked by Getsu Fuhma, Getsu Fuhma's effect is Step 1 of a chain because the turn player is Step 1, and Legendary Jujitsu Master is Step 2. Legendary Jujitsu Master resolves first and Getsu Fuhma is sent back to the top of the Deck, then Getsu Fuhma's effect resolves and Legendary Jujitsu Master is destroyed.
- If you have Destruction Punch's effect, and your opponent attacks your Legendary Jujitsu Master, you resolve the 2 effects in a chain with the controller (the defending player) choosing the order.
