THE FOG... OF WAR!!! - a new pool is created, containing:

Hefty, Grim Reaper, Terror Australis-Nemesis, Terminal Ferocity, Robogeddon, Forklift's Revenge, Stealth, Shrapnel, Kater Killer, Bumblebot

This removes Prometheus, Ming and SMIDSY from the pool, while Grim Reaper, Hefty and Stealth take their places.
