Edgar Markov + Oathsworn Vampire + Warren Soultrader + Thunder of Unity

Edgar Markov

Oathsworn Vampire

Warren Soultrader

Thunder of Unity

How it works

1. Cast Oathsworn Vampire either from your hand or graveyard by paying 1.
2. Edgar triggers, creating a 1/1 Vampire creature token.
3. When the Vampire and Oathsworn Vampire enter, Thunder of Unity triggers twice, causing you to gain 2 life and each opponent to lose 2 life.
4. Activate Warren Soultrader twice by paying 2 life and sacrificing Oathsworn Vampire and the Vampire token, creating two Treasure tokens.
5. Activate two Treasures by tapping and sacrificing them, adding 1.
6. Repeat.

This loop relies on Thunder of Unity's second and third chapters to constantly replenish your life total every time a creature enters the battlefield, turning life gain into the key that unlocks Oathsworn Vampire's ability to be recast repeatedly from your graveyard. As you cast the Vampire, Edgar Markov’s *Eminence* ability passively echoes the spell by spitting out an extra token, feeding both creatures directly into Warren Soultrader's altar. Sacrificing them both yields two Treasures whose mana covers the cost to replay Oathsworn Vampire, while the life gained from their arrivals safely offsets the costs paid to the Soultrader and the Saga, looping infinitely to drain your opponents dry.
