Another niche card that is a bit hard to understand for now. Tactic is one of the least interesting Trait since it only matters for Mark Harrigan but he already accesses 0-5, Chuck Fergus (so "Skids" O'Toole) but it's already fast and doesn't involve a test, Directive - Red Tape but again it's already fast and Sleuth but it's probably one of the least interesting 3-class talent.
So, why would you ever use this card??
The main issue is "At the end of the round", meaning after the enemy phase.
- Daniela Reyes can automatically evade an enemy with her . Trigger it with the Mechanic's Wrench and attack with it, applying the wound. Since your turns are often a bit empty, applying a DoT to an enemy and leaving to engage another one is potentially really good. And on top of that, lvl 0 cards are not so hard to slot in her.
- Survival Knife (0) if, for some reason, you are already considering getting some hits, you can now do so with a 3-hp enemy and kill it after you get attacked. It's not great, but if you planned on taking the Survival Knife already, then it's worth considering.
- Butterfly Swords allow you to perform the first attack on an enemy and the second on another one. So you could technically do the smaller attack combined with Grievous Wound on a bigger enemy and the 2-damage attack to defeat a 2-hp enemy and evade the wounded enemy. That is a veeeery niche situation since it requires you to have 2 enemies in play, one that justifies this and that you are able to evade after... Let's see what other cards come in this pack. As of now, I see an opportunity here, but not enough yet for something viable.
- As suggested in the comment by @Veronica212, "Skids" O'Toole could be somehow a bit interested, as he is more able than others to evade and leave the DoT behind. Cheap Shot (2) is a good way to add 1 damage and exhaust, and Switchblade, Enchanted Blade without using a charge as suggested. It doesn't save you much time unless you can change location and the enemy is not a hunter.
- In the same vein, William Yorick could see use with Stunning Blow, attacking with a Gravedigger's Shovel, Fire Axe without going down to 0 resources, Meat Cleaver without spending the Horror, etc... The problem is that you need both Stunning Blow and Grievous Wound in your hand at the same time, which can be complicated with the little Draw ability of Yorick.
- Honorable mention to Trusty Bullwhip would have been nice with this since you can attack, exhaust to evade and apply the bleeding.
Conclusion: As of now, except for Daniela Reyes, I wouldn't really consider this card yet, but that may change in the near future!
