William Mansfield "Willie"

Tinkerer's Insight — When Willie enters the battlefield, create a 1/1 colorless “Gadget” artifact creature token with “Sacrifice this: Draw a card.”

Backyard Architect — {2}, Tap an untapped artifact: Create a tapped Land token named
"Fire Pit" with "{t}: Add {r}."

If you control three or more gadgets, Willie gains flying and haste.
