The Boulder

Haste

Whenever The Boulder attacks, create a colorless Equipment artifact token named Rock with "Equipped creature has ' {1}, Tap, Sacrifice Rock: This creature deals
2 damage to any target'" and equip {1}. You may attach it
to The Boulder when it enters the battlefield without
paying its equip cost.

Whenever you're ready, The Pebble."
