Horn of the Mark
Riders of Rohan #17 (x3)
Attachment
[1]

Attach to a Rohan hero or Merry. Restricted.

Response: When a character leaves play, if that character shares at least one trait with the attached hero, exhaust Horn of the Mark to draw 1 card.

Then Éowyn gave to Merry an ancient horn, small but cunningly wrought all of fair silver with a baldric of green.
