The Mastermind of Life for the Ancients, Cygnus Prime for the Emergency Earth Coalition, and The World Spoiler for the Machine Horde. It was expected to be released in Feburary 2013, and would have included 150 cards.

BP 420, The World Spoiler
"Contaminate the atmosphere, pollute oceans, poison the ground, and wreak havoc on the ecosystem as the World Spoiler.  Lead your minions of world spoiling machines on a death march unlike any other, leaving both your opponent and the enviroment choking in your wake."

Cygnus Prime, World Wide Webmaster
"Erect impeneterable defenses and thwart enemy operations.  Control the flow of battlefield information and increase your defensive firepower through the world wide architecture of human technology as Cygnus Prime, administrator of Project ECHELON and World Wide Webmaster."

Mastermind of Life
"Manipulate the forces of both human and machine.  Take control of underlying genetic makeup of enemy troops, grossly blur the lines between life and artifice; summon plagues of experimental life forms as the Mastermind of Life."
