Light and Shadow is a small-box expansion to BattleCON (about 120 cards or so) that includes higher-powered versions of all Fighters and the cards necessary to play them. These can be used for 2v1 or 3v1 games, or you can use this expansion to duel two of these super-fighters against each other one-on-one.
The box will contain powered-up Unique Ability cards for each fighter in BattleCON: War of Indines and BattleCON: Devastation of Indines, as well as four new sets of bases: 2 sets of "EX" bases (used with EX ability cards, making a fighter roughly twice as strong as a normal character) and 2 sets of "Almighty" bases (used with Almighty ability cards, making a fighter roughly three times as strong as normal).
