Just to clarify, while a card that's immune to non-plot card effects can't be affected by non-plot cards, that immunity does not extend to the immune card's effects , does it? So, if a Lanni player triggers her HoD Iron Throne, for instance, that Response can be cancelled by HCiT, despite the immunity, yes?

It came up recently and I just want to make sure I had it right.

(3.19) Scope of Immunity

Immunity only protects a card itself. Peripheral entities attached to or associated with a card, such as attachments, duplicates, power counters, gold tokens on the immune card, and also including triggered effects originating from the immune card , can still be affected by cards of the type to which that card is immune , as long as the affecting cards do not target the immune card.

Thanks, ktom. I thought that I remembered that being in there but didn't have the FAQ handy when the question arose.
