Compared to Deathstrike, the main difference is that In Cold Blood is not a fast spell. It gains, however, 2 peculiar effects: the first and most important one is that it will kill, discard and give Voidbound to every copy of the target unit as long as it has a single influence; the second is that it does not allow the player to run it in any -based decks.
In Cold Blood is usually a good card in most decks, as the upsides greatly cover the downsides when compared to Deathstrike: either there won't be a great difference outside of not being a fast spell, either it hurts specific decks, especially those that rely a lot on specific units.
To get the most out of this card, one should prioritize (unless the match state forces otherwise) units with Revenge, Aegis or with powerful effects in general. For the first ones, there are units like Crownwatch Press-Gang, Elias, the Broken Wing, Stonepowder Alchemist and (most importantely) Inquisitor Makto. For the second ones, units like Crownwatch Paladin, Kosul Battlemage, Sheriff Marley, Icaria, the Liberator and Shelterwing Rider can be good targets, but only if you manage to remove their Aegis beforehand. If playing Stonescar, having Yushkov, the Usurper already on board can help greatly. For the last ones, units like Tavrod, Auric Broker, Rizahn, Greatbow Master, Telut, Queen's Hand and Amilli, Cloudmarshal can be locked away from the match together with the value they may generate.
Remember that Winchest Merchant is a unit, which means that killing it with In Cold Blood will essentially lock the market for your opponent.
You can play this card even if you don't have Justice influence to lose.
