Kodama and Sarinth Greatwurm's first ability trigger.
Resolve the Kodama trigger, choosing to put nothing onto the battlefield from your hand.
Holding priority, activate the basic Forest by tapping it, adding .
Resolve the Sarinth Greatwurm trigger, creating a tapped Powerstone artifact token.
When the Powerstone token enters the battlefield, Kodama triggers.

This ingenious loop turns a simple land drop into an endless cascade of triggers by using Kodama of the East Tree as the engine that constantly drops what Living Twister picks back up. As the Forest bounces and re-enters the battlefield, Sarinth Greatwurm watches every single arrival to continuously churn out tapped Powerstone tokens. Because each new token counts as a permanent entering under your control, it resets Kodama of the East Tree's trigger condition all over again, creating a self-sustaining loop that yields infinite landfall triggers and a massive army of artifacts.
