Oathsworn Vampire + Phyrexian Altar + Stormscape Familiar

Oathsworn Vampire

Phyrexian Altar

Stormscape Familiar

2. Cast Oathsworn Vampire from your graveyard by paying .
3. Repeat.

This elegant loop transforms the life-gain condition of Oathsworn Vampire into a self-sustaining sacrifice engine, provided you have a way to trigger its graveyard-casting ability.

Meanwhile, Stormscape Familiar quietly does the heavy lifting behind the scenes by reducing that casting cost, allowing the loop to break even on mana rather than bleeding you dry.
