I've never found myself using Quick Strike, despite it's awesomeness. There was a lot of controversy over this an the subject of immune to player card effects enemies, but the confusion passed. Note that it's not restricted to enemies engaged with you, so Haldir, Legolas, Brand, Bard, Dunhere, or any good ranged attacker are great candidates for this. My personal favorite target is Gimli. Muah ha ha haha!
Action: Exhaust a character you control to immediately declare it as an attacker (and resolve its attack) against any eligible enemy target.
Core Set #35. Tactics.
I found this card very useful only recently and since then i put it to decks right next to the Feint cards. Best events in sphere so far for me. The artwork is somehow strange, cause I'm not sure if the Orc already lost his head, or if he's going to be attacked from behind. And the vampire teethes...looks strange. Anyway. Verdict: 4/5.
