This loop relies on a brilliant little mechanical dance between land manipulation and untapping effects. With **Retreat to Coralhelm** sitting on your board, every time a land enters the battlefield, its landfall ability triggers to untap **Skyshroud Ranger**, which immediately lets you tap **Skyshroud Ranger** again to put that very same land right back onto the battlefield from your hand. To keep the engine moving, **Trade Routes** steps in with its first ability, allowing you to pay {1} to bounce that land back to your hand whenever you need to reset the cycle. Together, this trinity creates an endless loop of lands entering and leaving the battlefield, generating infinite landfall triggers to fuel your victory.
