Ren the Unclean wrote:Unique. Nazgûl (8th). May be played as a hazard creature (with one strike) or as a permanent event. As a creature, may also be played keyed to Dagorlad, Ithilien, Gorgoroth, and Horse Plains; and may also be played at sites in these regions. If played as a permanent-event, it will remain in play until tapped during the opponent's movement/hazard phase (tapping counts against the hazard limit). When tapped, Ren the Unclean becomes a short-event; each character in play must make a corruption check.

I will start from Doors of Night. When DoN is declared it is not declared that resource X will be discarded, resource Y will be discarded... and so on.
All resource environment cards present at resolution of DoN will be discarded simultaneously. DoN does not target any of them, so if any of them will leave play between declaration and resolution, it will not fizzle the DoN. And if some will appear in play in meantime, it will be discarded.
Similarly Ren Unleashed refers to "All characters at the same site as Ren". Because playing Ren Unleashed does not cause declaration of cc for any specific character, there is no way to target (by tapping in support for cc, or by playing a resource") any cc caused by Ren Unleashed.
How tapping of Ren the Unclean does work?
In my opinion (and it does not contradict with CRF) it causes a serie of declarations of cc.
- if any of target of such cc will leave play between declaration and resolution of tapping the Ren the Unclean, it will not fizzle a whole serie, only one declared cc,
- any cc may be targeted by actions declared in response to the serie of declarations (there is no possibility to declare anything between particular ccs),
- any character that will appear in play after declaration of tapping the Ren the Unclean will not perform cc.
