This clever loop turns the self-bouncing drawback of Golgari Rot Farm into an engine of endless multiplication, completely enabled by Spelunking ensuring the land enters the battlefield untapped. With Dryad of the Ilysian Grove on the board to expand your land-play limits, replaying the Rot Farm triggers the landfall ability of Springheart Nantuko, which uses the generated mana to continuously stamp out token copies of your Dryad.
