Fast, testless damage is really good. But is it so good that it's worth paying this much for? The resource, card slot, and XP costs here are individually reasonable, but collectively steep.

Assuming they were going to attack anyway, guardians can already get extra damage without spending additional actions or taking additional tests with tools like Vicious Blow, and the new Hunter's Mark. Dynamite Blast and Counterpunch offer testless fast damage without even attacking, though they may require taking some damage first. If you're willing to keep swinging away with a melee weapon, cards like Galvanize and Flurry of Blows can pump out a lot of damage.

The resource discount here relies on drawing cards while enemies are around, which implies that you either need fast or opportunity-attack-ignoring draw options, or that you're not the one actually engaged with the foe. That suggests this kind shines best for those rare characters with level 3 guardian access who aren't likely to be built as main fighters, or who need help passing tests. Especially if their off class or ability provides lots of resource generation or draw power.

So maybe this is a card that Carson Sinclair, Sister Mary, Carolyn Fern, and Marion Tavares want to look at. It's going to be especially strong against enemies who reduce all damage to 1 anyway, or 1 point pings have special value for other reasons (such as revealing concealed decoys).

Sadly, although Boxing Gloves can find these for you, it doesn't "draw" them, so you'd need to be rich to make it work. I guess you can pay for them with Prophetic if you really want.

The cutest combo: Be Tommy Muldoon. Stuff three Quick Shot in your Hunting Jacket. Go Toe to Toe with the boss. Profit.

As it's not specified that you have to draw it from your deck, you can use Katja Eastbank to "store" the 3 copies of Quick Shot and then use her action to draw them during your turn. This way, for 1 action (her ability), you play Quick shot for free (the trigerred ability).

Of course, if you are engaged with the enemy you take an attack of opportunity, but it's in a Tommy Muldoon deck so you should be able to handle it and it works without AoO against Aloof enemies or enemies engaged with other investigators.

More costly than OrionAnderson's combo with Hunting Jacket (resource- and action-wise), but with the added benefit that you replace the - then useless - draw of Quick Shot by the draw of an other card.
