Holon Energy GL provides C Energy. If the Pokemon that Holon Energy GL is attached to also has a basic G Energy card attached to it, that Pokemon can't be affected by any Special Conditions. If the Pokemon that Holon Energy GL is attached to also has a basic L Energy card attached to it, damage done by your opponent's Pokemon-ex is reduced by 10. Ignore these effects if Holon Energy GL is attached to Pokemon-ex.
