This looks like a great card with cool abilities for high Agility rogues, but in practice I found it disappointing. First you need to get it and a gun played. Then you realize it exhausts, so if the first shot misses or fails to kill the target you need a back up source of damage. Tony isn't going to bother with it.
It's much too expensive for its limited usefulness.
The Ornate Bow is still a better weapon for this role.
