Valkyrie's Call + Simulacrum Synthesizer + Shilgengar, Sire of Famine

Valkyrie's Call

Simulacrum Synthesizer

Shilgengar, Sire of Famine

How it works

1. Cast the Vehicle by paying its mana cost.
2. When the Vehicle enters the battlefield, Simulacrum Synthesizer triggers, creating a 0/0 Construct artifact creature token that gets +1/+1 for each artifact you control.
3. Activate the Vehicle's crew ability by tapping the Construct, causing the Vehicle to become an artifact creature until end of turn.
4. Activate Shilgengar by sacrificing the Vehicle.
5. When the Vehicle dies, Valkyrie's Call triggers, returning the Vehicle from your graveyard to the battlefield. It will not be an Angel because the Vehicle is no longer a creature and cannot gain creature types.
6. When the Vehicle enters the battlefield, Simulacrum Synthesizer triggers, creating a 0/0 Construct artifact creature token that gets +1/+1 for each artifact you control.
7. Resolve the Shilgengar ability.
8. Repeat from step 3.

This loop relies on transforming a single artifact into a relentless engine of sacrifice and resurrection, fueled by Simulacrum Synthesizer's ability to flood the board with growing Construct tokens every time your hardware cycles back into play. By using Shilgengar, Sire of Famine to sacrifice the crewed Vehicle, you trigger Valkyrie's Call to instantly rescue it from the graveyard, bypassing its creature status upon return so it can safely re-enter and trigger the Synthesizer anew. Meanwhile, Shilgengar’s ability churns out a steady supply of Blood tokens from those sacrifices, eventually allowing you to cash in six of them to resurrect your entire graveyard all at once.
