Gwemegil is a formidable weapon, granting not only the standard unique weapon bonuses but also helping card flow and making Arwen harder to overwhelm. This card can be used to discard unneeded cards from your hand, allow Arwen to survive large minions such as the Balrog and can help her to win skirmishes. It is also more versatile than Asfaloth, as it is not discarded at underground sites. Besides those benefits, it's the only card in FOTR block to provide a damage bonus (is the only card along with Erethon in all sets to do so).

This card stays relevant well into the later sets, as it is easily more powerful than the generic Elven Sword, and its only true competition comes from Hadafang in Expanded. Like Elven Sword, it can be used with Initiative effects such as Glimpse of Fate from Mount Doom (set 10) for a powerful effect.
