Skittering Precursor + Sword of the Meek + Nahiri's Resolve + Grinding Station

Skittering Precursor

Sword of the Meek

Nahiri's Resolve

Grinding Station

How it works

1. Activate Grinding Station by tapping it and 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 Nahiri's Resolve, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Eldrazi Spawn.
4. When Sword of the Meek enters the battlefield, Grinding Station triggers, untapping Grinding Station.
5. Resolve the Grinding Station ability from step 1, causing a player to mill three cards.
6. Repeat.

This loop turns the recursive nature of Sword of the Meek into a milling machine by leveraging Grinding Station as both the sacrifice outlet and the payoff, untapping itself every time the sword returns. Skittering Precursor acts as the crucial bridge, converting that sacrificed artifact into an Eldrazi Spawn token rather than leaving you empty-handed. Meanwhile, Nahiri's Resolve quietly ensures that the newly created token enters the battlefield with a power and toughness boost, making it a 1/1 so that Sword of the Meek's resurrection trigger successfully fires.
