Valkyrie's Call + Simulacrum Synthesizer + Viscera Seer

Valkyrie's Call

Simulacrum Synthesizer

Viscera Seer

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 Viscera Seer 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 Viscera Seer ability.
8. Repeat from step 3.

This intricate loop turns the continuous rebirth of a crewable Vehicle into an engine for endless value, orchestrated by Valkyrie's Call to continuously pull the fallen machine straight back from the graveyard with each trip. As the Vehicle repeatedly re-enters the battlefield, Simulacrum Synthesizer notices the arrival of an artifact with a mana value of 3 or greater, flooding your board with an endless army of growing Construct tokens. Meanwhile, Viscera Seer provides the essential sacrifice outlet to send the crewed Vehicle to the graveyard while smoothing out your draws with infinite scry triggers along the way.
