Underworld Breach + Diligent Excavator + Thassa's Oracle + Vesuvan Doppelganger
How it works
- Cast the artifact creature from your hand by paying 0.
- Diligent Excavator and Vesuvan Doppelganger trigger, causing you to mill four cards.
- The artifact creature enters the battlefield and dies as a state-based action due to having zero toughness.
- Cast the artifact creature from your graveyard for its escape cost by paying 0 and exiling any three cards from your graveyard, except Thassa's Oracle if it is in your graveyard.
- Repeat from step 2 until you have an empty library.
- If Thassa's Oracle is in your hand, cast it by paying .
- Otherwise, cast Thassa's Oracle from your graveyard for its escape cost by paying and exiling three cards from your graveyard.
- Thassa's Oracle enters the battlefield, causing you to win the game.
This ingenious loop relies on Underworld Breach to turn your graveyard into a second hand, allowing you to repeatedly cast a zero-mana artifact creature for its escape cost by feeding away extra cards. As you churn that creature in and out of the graveyard, Diligent Excavator turns every single casting into a mill trigger that quickly feeds the Breach's exile requirement and strips your library bare. Meanwhile, Vesuvan Doppelganger joins the fray as a clever multiplier, copying the Excavator to double your milling speed and ensuring you tear through your deck even faster. Once your library is completely empty, you finish the game by casting Thassa's Oracle, whose enters-the-battlefield trigger sees your devotion to blue easily outnumber your zero remaining cards and claims immediate victory.
