Land Equilibrium

Enchantment, 2UU (4)
If an opponent who controls at least as many lands as you do would put a land onto the battlefield, that player instead puts that land onto the battlefield then sacrifices a land.¹
Illus. Jesper Myrfors

Gatherer Card Rulings [Nov 2009]

• 10/4/2004: You sacrifice a land after you put one into play and not before.
• 10/4/2004: This is a replacement effect, so it is not possible to tap the land that just entered play for mana (as a mana source) before you sacrifice a land.
