This crafty little loop turns a simple bounce land into an endless replication factory, leaning heavily on The Wandering Minstrel to bypass the usual tempo penalty by letting your lands enter untapped right away. As Selesnya Sanctuary bounces itself back to your hand over and over, its repeated arrivals trigger Springheart Nantuko to continuously churn out fresh copies of Icetill Explorer by paying the landfall cost. Meanwhile, Icetill Explorer's own abilities let you keep replaying that very same Selesnya Sanctuary from your hand turn after turn, sustaining the loop while self-milling your deck into oblivion.
