That ruling clearly indicates that these are Triggers and do indeed activate and create Chain Links.[Re: Legendary Jujitsu Master] If "Legendary Jujitsu Master" is changed to a Fiend-Type or a Zombie-Type 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.
