One question we had during the European championship was: Is Claret Knight immune to indirect triggered effects (effects that target the player and oblige him to do something on one of his character like Temple of R'lyeh or Initiate of Huang Hun or Echanted Wood + Deranged Diva )
If I quote the FAQ on immune (2.36)
Some cards have the card text “Immune to X” in their text boxes. This means that they cannot be targeted by cards with that subtype and/or card type. This also means that if a card with that subtype and card type does not target a specific character, but affects all characters or a group of characters, these cards ignores that effect. A character can never be immune to its own effects.
It could be understood as "if you don't specifically target the card, then immunity doesn't work".
When FFG designed Claret knight, did you intend to immune it against any type of triggered effects ( Bold word : XXX) and may be we need to modify/complete the immune part in FAQ? Or did you plan to protect him only against specific target triggered effects and indirect triggered effect could work?
