The Superhuman mobs are each 3d10 in their affiliation dice, so there are actually 9 affiliation dice in play total:<br/><br/>Superhuman Mob 1: Team 3d10<br/>Superhuman Mob 2: Team 3d10<br/>Superhuman Mob 3: Team 3d10<br/><br/>was how the scene started (and I could have made that clearer, for which I apologize)<br/><br/><br/>As for the doom spending, the supermen mobs have been receiving doom dice for taking d4 distinctions, buying off player opportunities, and spending effect dice to add to the doom pool, representing their success at damaging the city.  The doom pool generally goes up, rather than down during play, and generally represents how well the heroes are doing fighting villiany at any given moment.  Many times, attacking a powerful enemy will only damage the doom pool, which also represents the threat level of the plot.  If the doom pool climbs enough to contain 2d12, it's a sufficiently doomy situation for the scene to immediately end, if the GM chooses.
