possibly the dumbest life gain deck I've made yet.

Oketra's Monument + Whitemane Lion is the primary bounce engine for the deck with it you can quickly get storm triggers for Aetherflux Reservoir as well as lots of life gain fromSoul Warden and Soul's Attendant.

Whitemane Lion can also be used to bounce any creatures your opponents try to remove so it's best to wait until your opponent is either ending their turn or killing your things before you use it.

if you have the money Archangel of Thune is a great addition to the deck.
