Clown Car + Salvaging Station + Battered Golem + Altar of Dementia

Clown Car

Salvaging Station

Battered Golem

Altar of Dementia

How it works

1. Activate Salvaging Station by tapping it, returning Clown Car from your graveyard to the battlefield.
2. When Clown Car enters the battlefield, Battered Golem triggers, untapping Battered Golem.
3. Activate Clown Car's crew ability by tapping Battered Golem, causing Clown Car to become an artifact creature until end of turn.
4. Activate Altar of Dementia by sacrificing Clown Car.
5. When Clown Car dies, Salvaging Station triggers, untapping Salvaging Station.
6. Resolve the Altar of Dementia ability, causing target player to mill cards equal to Clown Car's power.
7. Repeat.

This clever loop puts Salvaging Station at the center of a tireless recursive engine, using its tap ability to resurrect Clown Car from the graveyard for a mere single mana value. Every time that little Vehicle drops onto the battlefield, Battered Golem's passive trigger notices the incoming artifact and springs upright to help, allowing it to easily tap to crew the Clown Car and turn it into a creature. From there, you feed the freshly crewed vehicle to Altar of Dementia to mill an opponent, sending the Clown Car straight back to the graveyard. That very same death triggers Salvaging Station to untap itself, resetting the whole cycle so you can loop it indefinitely.
