Survival

All creatures turn into 1/1 battle droids for the remainder of the game. All players have their health reduced to 1. When a Sorcery, instant,artifacts or Enchantments that deal damage is casted it is negated and exiled. When a creature enters the field it turns into a 1/1 battle droid. When Survival is destroyed, exile it instead and creatures are turned into what they were before.
