Firearms get a shot in the arm.
There are a lot of good things to say about Marksmanship. To be concise, this card is an action saver. At its best, it can save you over a turn of actions (MOVE to connecting location, ENGAGE an enemy off an ally/an aloof enemy, FIGHT for 2ish damage and FIGHT to finish off a foe) and at its worst, it saves you two actions, which is still really good.
It is a tactic, so it can be played off of Stick to the Plan, meaning you will always have it in your back pocket.
And really, the only thing that this requires of you is to run guns... which have gotten a lot better thanks to Venturer and Stick to the Plan (with Extra Ammo).
Oddly enough, this card is probably best in Rogue who can double or nothing with this and really put the hurt on a boss, from afar.
A great card, well worth the xp!
Oh and don't be fooled by the art. Don't use this with barricade and the springfield (my heart wants them to be playable!).
