Xavier Sal, Infested Captain + Intruder Alarm + Bristly Bill, Spine Sower + Jyoti, Moag Ancient

Xavier Sal, Infested Captain

Intruder Alarm

Bristly Bill, Spine Sower

Jyoti, Moag Ancient

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 Bristly Bill trigger.
3. Resolve the Bristly Bill trigger, putting a counter on a creature you control.
4. Resolve the Intruder Alarm trigger, untapping all creatures.
5. Repeat.

This engine harnesses the relentless synergy between token generation and untapping to spiral completely out of control. With Intruder Alarm on the battlefield, every single creature entering the battlefield immediately untaps all creatures, including Xavier Sal, Infested Captain—whose tap ability is continuously fueled by consuming counters and populating more Forest Dryads. Meanwhile, Bristly Bill, Spine Sower feeds this loop by dropping a counter on itself every time a land creature enters, ensuring Xavier Sal always has a counter available to remove while simultaneously growing your army alongside Jyoti, Moag Ancient.
