Following the same logic, one could ban necromancy in Castle, 8mm6, and all subsequent versions.
In Castle, 8mm6, and other tournaments, there is no objective to force or compel a player to start using demons. However, this tournament specifically focuses on that. The possibility of using necromancy reduces the likelihood that players will start using demons. If the goal is to determine who is better at using demons, then banning necromancy is logical. It's not being banned for the template, but for the tournament.
