As also mentioned in the editorial comments of the URD, this question was asking if WHCTK can bring in your Ringwraith Avatar (just as the previous question asked by the same person was whether or not A Chance Meeting could bring in your Wizard).3.) We have come to kill
May I use this card to bring my ringwraith in play ? And what will be the amount of his mind ? May I use ACM at any time during my turn (during movement hazard phase to assign the new character a strike; will this increase the number of hazards) ? May I play a character (during organisaton phase) at any shadow-, borderhold and ruin & lairs also if the site is not in play ?
No, We have Come to Kill can't be used to bring in a Ringwraith. The same restriction applies that you must be at the site.
As such, it is unclear whether or not WHCTK can be used to bring in a Ringwraith follower.
As I believe it provides for more interesting game play and is consistent with the current interpretation that ACM/WHCTK strictly prohibits bringing in one's Avatar, but not any other characters, I propose the following clarification be issued for this card:
We Have Come to Kill -
May be used to bring in a Ringwraith follower. All Ringwraith follower restrictions must still be observed, except for the site and phase restrictions.
