One of the most spectacular uses I've found for this card is in a multiplayer game in Khazad Dum/Dwarrowdelf cycle, when players tend to get overrun by a swarm of low-health enemies: play The Hammer-stroke during a critical moment of the scenario and then use Boromir's ability to discard him and deal 2 damage to each enemy that you've just engaged (it works even better if someone uses Thalin and can exhaust some ranged character to play Rain of Arrows). Not only is this extremely thematic "last stand" for this character, but this sacrafice often allows the group to make a final push and win the game. This was one of the most exciting and satistyfing moves I managed to pull off in this game. Ever.
