Just tested out the new HG Sword, and here are a few mildly disappointing facts:
-> It will only store the FIRST unit you kill with the sword.
-> Successive kills by the card doesn't store more units or change the stored unit.
-> The first use DOES NOT spawn the stored unit, so it only works as a 5-Damage card on first use.
-> Just in case you read through the card text too fast, you don't need to kill a unit on the second use to spawn the stored unit.
Maybe it's just me who thought it would work a bit similar to Coup, or was hoping it could store more units if you built around it (I got to use HG Sword 5 times in one game in NG). I guess the real upside on this sword is that if you somehow kill a high value unit, you can potentially replay it multiple times.
