Realm of Purged-Birth

Once per duel, if a player's life is to be reduced by card effect, you may instead
reduce the life of you and your opponent by double the original amount.
"Some of our Dragon-Lords wish for Rule; others instead wish the world to be remade. Yet, to
the ancients, there can be no creation without
first destruction." -From the Draconium Universalis; Text of the Dragon Priests.
