Construct Farmhouse

Plains Fortify {1}{w} ({1}{w}: Attach to target plains you control. Fortify only as a sorcery.)
As long as the permanent is fortified, it loses
all card types and is a building with "At the beginning of your upkeep, you gain 2 life and create a 1/1 white citizen creature token."
(Building is a type of card that exists only on
the battlefield. It's not a land.)
