2. When you sacrifice Sword of the Meek, Szarel triggers, putting a number of +1/+1 counters on Scurry Oak.
3. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
4. When the Squirrel enters the battlefield, Sword of the Meek triggers, returning itself from your graveyard to the battlefield attached to the Squirrel.
5. When Sword of the Meek enters the battlefield, Grinding Station triggers, untapping Grinding Station.
6. Resolve the Grinding Station ability from step 1.
7. Repeat.
