This loop relies on a brilliant life-manipulation engine where Selenia, Dark Angel acts as your own worst enemy and your greatest catalyst, letting you repeatedly pay 2 life to bounce her back to your hand. Every single payment feeds directly into Vilis, Broker of Blood, whose triggered ability translates that life loss into a flood of drawn cards. Those newly drawn cards immediately wake up Sheoldred, the Apocalypse, whose passive triggers pump your life total right back up and keep you safely in the black. Together, these three legendary threats create a self-sustaining cycle that nets you massive card advantage and boundless life whenever you choose to set it in motion.
