Introduction
Battle Box is a format where everyone plays from a shared deck, and has access to the same kinds of lands. All the cards should be on an even power level so it is more of a test of skill than the power level of the cards and deck.
Judge Tower is a variant of Battle Box, where as soon as you make a mistake you lose, its very punishing but a very good test of skill and will help you improve fast.

The deck is full of cards with hard to remember effectsc, so the main aim is just to stay alive. The rules of how to play are in the link below.
