Picked up a capacitor, though I had to sacrifice all of my expendable trade bait for it. This list had better not be a waste of time, because I have everything needed now. :V
uh... You did waste all that trade swag.
When all the items on the list were crafted together, the game created a system-wide message alerting everyone to the Blood Brothers comic.

Looking at
the enemies list, pyros and especially spies are going to be near useless against the robo-horde. Maybe Pyros may be useful for knockback if they start to get too close. Standard Engies with a Wrangler and a full nest, otoh, could be invaluable.
Something tells me the best balance will be the 6 shown in the trailer; Medic, Engie, Heavy, Demoman, Soldier, and Scout. Though the Scout could probably be swapped for a sniper or pyro.
