Doc Aurlock, Grizzled Genius

Phyrexian Altar

Oathsworn Vampire

How it works

1. Activate Phyrexian Altar by sacrificing Oathsworn Vampire, adding .
2. Cast Oathsworn Vampire from your graveyard by paying .
3. Repeat.

This brilliant little necromantic loop hinges on Doc Aurlock, Grizzled Genius and his uncanny ability to slash the casting costs of spells from exile or your graveyard by {2}. Because Oathsworn Vampire normally costs {1}{B} to cast, that hefty discount means it now costs just {B} to rise from the dead—making its recursive resurrection completely free. Once it hits the graveyard, you simply sacrifice it to Phyrexian Altar to generate the exact {B} mana needed to cast it all over again. Along the way, Oathsworn Vampire's self-contained lifegain trigger naturally satisfies its own condition to keep crawling back from the graveyard, feeding the Altar for an endless stream of sacrifice, entry, and death triggers.
