This trait is probably not self explanatory so here goes. So there are these troops in game that cause you to give up a troop. This could be black beast, sac priest or a certain statue. For the sake of synergy, i offer you "Pawn"
Pawn is an on death affect that only works if killed on the player’s turn. This could be something like, resurrect if sacrificed or devoured (in the case of black beast) or give its stats to other troops in your team. Each troop with “pawn” would have an effect that helps them in game, but who really shine after being sacrificed. With the disliking of on death effects going awry, this would be a skill that might take some programing time to make, and to implement without bugs.
What do you think? Is this crazy enough to work, or is it just plain crazy? Leave your thoughts down below!
