Filthy Pirates

When an opponent's Freighters fly (or MULEs walk) through their area of effect, Filthy Pirates will steal up to half of their contents if they are not on cool-down (6 in game ticks which at normal game speed is 6 seconds). They will continue to plunder until 200 units of a resource are stolen. Filthy Pirates are unaffected by Magnetic Storms. They must be placed on an unused tile and can be crushed (removed) if a player constructs a building on that tile. The resources stolen are instantly added to your stockpile.
