Sigma and a selection of Mavericks and stage enemies from the Mega Man X series play a predominant role in the second part of the "Echoes of the Lost Civilization" trilogy. You can expect a lot of Mega Man X-themed cards after the break!
On a final note, the new supplemental cards slated for December will bring another character from Rockman X DiVE after RiCO's appearance in the card pack Defying the Light. It's none other than White Day Alia. You can see her in the top left corner in the image above.
