Kolodin, Triumph Caster + Salvaging Station + Viscera Seer + Consulate Dreadnought

Kolodin, Triumph Caster

Salvaging Station

Viscera Seer

Consulate Dreadnought

How it works

1. Activate Salvaging Station by tapping it, returning Consulate Dreadnought from your graveyard to the battlefield.
2. When Consulate Dreadnought enters, Kolodin triggers, causing Consulate Dreadnought to become an artifact creature until end of turn.
3. Activate Viscera Seer by sacrificing Consulate Dreadnought.
4. When Consulate Dreadnought dies, Salvaging Station triggers, untapping Salvaging Station.
5. Resolve the Viscera Seer ability.
6. Repeat.

This loop turns the massive crew requirement of Consulate Dreadnought into an irrelevant hurdle by bypassing it entirely, letting you sacrifice the Vehicle over and over again to Viscera Seer. The trick relies on Kolodin, Triumph Caster to instantly animate Consulate Dreadnought the moment it enters the battlefield, which allows it to be sacrificed immediately as a creature rather than having to wait around to be crewed. Once it hits the graveyard, Salvaging Station pulls it right back to the battlefield, and its death trigger simultaneously untaps Salvaging Station so you can repeat the process indefinitely while digging through your deck with scries.
