Xavier Sal, Infested Captain + Intruder Alarm + Jyoti, Moag Ancient + Prowling Felidar

Xavier Sal, Infested Captain

Intruder Alarm

Jyoti, Moag Ancient

Prowling Felidar

How it works

1. Activate Xavier Sal by tapping it and removing a counter from a permanent you control, creating a token copy of the Forest Dryad token.
2. When the Forest Dryad enters the battlefield, Intruder Alarm and Prowling Felidar trigger.
3. Resolve the Prowling Felidar trigger, putting a counter on a creature you control.
4. Resolve the Intruder Alarm trigger, untapping all creatures.
5. Repeat.

This clever token engine transforms Jyoti, Moag Ancient's initial command zone presence into an unstoppable wave of life by continuously reproducing the Forest Dryad land creature tokens. Xavier Sal, Infested Captain acts as the mastermind of the operation, tapping to strip a counter from Prowling Felidar—which passively grows larger via its own landfall ability—in order to populate another Dryad copy. Every time a new Dryad hits the battlefield, Intruder Alarm's static untap ability triggers from the creature entering, refreshing Xavier Sal and your entire board to keep the loop going indefinitely.
