Benefits any weapon-based strategy, but works particularly well with weapons, serving as a cheap Relics of Moria, or with Nazgul for Morgul Blade. The site is quite early in the game for weapon recursion however, requiring that weapons be already in the discard pile before it can be used, so it may fail if weapons have not yet been drawn. It can be contrasted with Moria Stairway, which provides a bonus for existing weapons instead, and only requires that weapons have been drawn by site 4, rather than played or discarded.
