Valkyrie's Call + Simulacrum Synthesizer + Goblin Bombardment

Valkyrie's Call

Simulacrum Synthesizer

Goblin Bombardment

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 Goblin Bombardment 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 Goblin Bombardment ability.
8. Repeat from step 3.

This loop turns your Vehicle into an engine of endless destruction and growth, fueled by the relentless pressure of Goblin Bombardment to sacrifice the artifact creature for direct damage. Each time the Vehicle dies, Valkyrie's Call immediately rescues it from the graveyard and brings it right back to the battlefield, bypassing any permanent loss. That recurring entrance triggers Simulacrum Synthesizer over and over again, flooding your board with a massive army of growing Construct tokens while continuously feeding your sacrificial loop.
