This ingenious loop turns a simple bounce land into a token-generating engine by stacking continuous land drops and untap replacement effects. With Spelunking ensuring Gruul Turf enters the battlefield untapped instead of slowed down, you can tap the land for mana in response to its own self-bounce trigger. Meanwhile, Dryad of the Ilysian Grove grants you the extra land drop needed to replay Gruul Turf endlessly, while Springheart Nantuko capitalizes on each new land arrival by paying to clone your Dryads.
