Coldhands can only be triggered if you have another character to remove from the game.
Duplicates can be used to save from "remove from the game" effects.
Removed characters return to play after Coldhands has already left play (so no combo with Ramsay Snow).
Removed characters return to play under their original owners' control.
- If you play Mutiny at Craster's Keep and sacrifice Coldhands as a cost, removed characters return to play in time for the choosing of targets, however they are not eligible due to the Jeyne Westerling rule (FAQ 3.2).
