Skittering Precursor + Sword of the Meek + Weapons Trainer + Phantom Train

Skittering Precursor

Sword of the Meek

Weapons Trainer

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Sword of the Meek.
2. Skittering Precursor triggers, creating a 0/1 Eldrazi Spawn creature token.
3. When the Eldrazi Spawn enters the battlefield as a 1/1 due to Weapons Trainer, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Eldrazi Spawn.
4. Resolve the Phantom Train ability
5. Repeat.

This intricate engine transforms simple sacrifices into an unstoppable loop by weaponizing the passive board state provided by Weapons Trainer, whose static buff to your 0/1 tokens is the secret key that makes everything work. When you use Phantom Train to sacrifice Sword of the Meek, Skittering Precursor instantly replaces it with an Eldrazi Spawn token. Thanks to Weapons Trainer boosting that token's power and toughness, the newly created creature enters the battlefield as a 1/1, which immediately satisfies Sword of the Meek's resurrection trigger and returns the Equipment right back to the battlefield attached to your token. Because the Eldrazi Spawn can then sacrifice itself for colorless mana or be fed back into Phantom Train, you generate boundless resources, triggers, and a massive +1/+1 counter growth on your Vehicle.
