Sly Requisitioner + Sword of the Meek + Grinding Station

Sly Requisitioner

Sword of the Meek

Grinding Station

How it works

1. Activate Grinding Station by tapping it and sacrificing Sword of the Meek.
2. Sly Requisitioner triggers, creating a 1/1 Servo artifact creature token.
3. Sword of the Meek triggers, returning itself from your graveyard to the battlefield attached to the Servo token.
4. Sword of the Meek enters the battlefield, triggering Grinding Station, untapping Grinding Station.
5. Resolve the Grinding Station ability from step 1, causing target player to mill three cards.
6. Repeat.
