“Batteryman” is an archetype of LIGHT Thunder monsters that was originally released in 13th Main Box: Burning Nova and that has recently received further support in the form of Batteryman 9-Volt and Batteryman Fuel Cell. Although the deck still seems to struggle against some of the most prominent threats in the meta, it has notably improved, being able to bring out one of its main win conditions consistently with very little investment.
