Has anybody heard of a card game called predator-prey? It probably would be considered an educational game, and came with special cards with either "predator", "prey", or "death and decay" on each card. I am trying to find it as a Christmas gift, but haven't been able to find it. I swear it was around in the 90's?

Thanks!
