This card is yet to see play, but so far I like it.. and also find it really weird.
So this is basically a deadlier and costlier Ornate Bow, which uses Strength, almost guarantees hit and one-shots most of the enemies in the game. And, for 5 XP, it should serve as your main big weapon.
Yet it has this weird "Hunter, Veteran, Warden only" restriction. Most of this guys are guardians or guardian-ish, and... they honestly don't need this gun.
Full guardians have decent Strength so big boost don't really matter to them. And they have strong in-class competitors, which lack "endless" ammunition, but at least they can reload it with guardians cards, as with Bow.
Guardian-ish greens who cat take it (Tony Morgan and upcoming Michael McGlen) also have 5 Strength. I guess they can fit in more actions to reload this thing with their tech, and use 10 to-hit on Expert Bag? But they lack tutoring for weapons Guardians have.
So investigators that want this card the most are ones with no comparable in-class weapons, low-to-mediocre Strength so they'll appreciate boost and readiness to dedicate hands to holding an anti-tank rifle. Which, among all investigators with Hunter, Veteran or Warden traits leave us with exactly one option! Sole hero, for whom this card is intended to be given. Some might even say it was godsend.
Enter Father Mateo, The Priest, Believer, Warden. Who needs holy books that take away your Elder Sign when you have Tankgewehr? Mateo even got XP to spare at start of the campaign!
Yeah, it's a weird card.
