Can i save a unique character wiht a dupe?

if i play another copy of a character that have Cold hands removed previously and my new copy dies and after that i kill cold hands, My died character comes to live again?

No. That copy of that character remains out if the game permanently. Its almost exactly like what happens with a dead character that is still in the shadows. They can't be taken out.

Also I'm assuming you are talking about a unique character.

(You can save a unique character from Coldhands' "remove from play" effect with a dupe.)

Bomb is correct. If there is a copy of a unique card in your dead pile, any attempt to being a second copy into play under your control fails.

Hate to ask KTOM, but are you definately correct?

Watched the most recent chapter pack unboxing (Team Covenent) and they weren't sure but suggested FFG has said that duplicates do not save "remove from play" effects

I also assume that this new Coldhands ability allows you to select himself (card text etc. is not on CardGameDB yet)

i.e. I am assuming that I could play the plot "First Snow of Winter" (When the first challenge is initiated this round, return all characters with printed cost 2 or lower to their owners' hands), play Coldhands during marshelling and remove from play one of each of my openents characters (discarding all dupes, attachments and power) and discard my own Coldhands

The other characters would come into back into play and then when the first challenge is initiated, Coldhands returns to my hand

This is not ambiguous:

(4.2) Duplicates The text from page 19 of the Rulebook should read: “If one of your unique cards is about to leave play, as a triggered ‘Response:’ effect, you may discard an attached duplicate to save the unique card from leaving play. This includes, but is not limited to, an effect that kills, discards, returns the card to hand, deck, shadows, or removes the card from the game.”

As Grimwalker quotes, there is no doubt that dupes can save from being removed from the game - by Coldhands or any other means.

If Coldhands chooses himself as one of the characters that is removed form the game, the "return to play" part of his effect kicks in immediately and the chosen characters (including Coldhands) go into a "moribund:return to play" state (as described in the FAQ that people point to as an explanation of how "Call of the Three-Eyed Crow" works). Since all of these characters (including Coldhands) are considered to have left play, they will lose all power, attachments, lasting effects, etc., as well as stand and have all limits reset when they "return to play." They are, from that point on, "in play," and you can do what you want with them.

"All limits reset"?

I was asking about Ser Greenfield's ability and from the responses there, I would expect the limits not to reset

i.e.

1) Preson Greenfield triggers his ability to return a Kinguard to shadows

2) He then gets removed from play via Coldhands

3) He comes back into play during the same round

4) ... he can trigger his ability again?

I can see that this scenario is different from Preston using his own ability to return himself to shadows and then pops out again but not sure what difference is actually causing the change to what is or isn't limited

The rule is that if a card removes itself from play, any limit will apply to all cards with the same name. Otherwise, the limit applies only to the original card.

When a card leaves play and is then returned to play, even if the players are sure it is the same piece of cardboard, the game has no concept of it. Each time a card enters play, it is considered a "brand new" card.

- So, when Preston removes himself from play, he falls under the "self-removal" part of the rule and the limit applies to all cards named "Ser Preston Greenfield." So, when he returns to play as a "new" card with the same name, the limit applied. This is true no matter how he leaves and returns to play. (So, if he returned himself to Shadows, came back out of Shadows, was removed by Coldhands, then returned when Coldhands leaves play - all in the same round - the "self-removal" rule still applies to the "new" Preston Greenfield from back when he originally removed himself.)

- BUT, if Preston removes some other character from play, that does not fall under the "self-removal" part of the rule and the limit is only applied to the "specific" Ser Preston Greenfield who returned the other card to Shadows. When he leaves play and returns as a "new" card with the same name, the limit from the "old" card does not apply, and the limit is effectively "reset."

What section of the FAQ is that? I believe you. I'm just wondering for reference as I don't recall reading it.

FAQ 4.22 outlines the rule for limits. Recognizing that the rule applies to Preston Greenfield somewhat differently depending on the target chosen for his ability is directly derived by applying the rule.
