Xavier Sal, Infested Captain + Intruder Alarm + Staff of Titania + Roaring Earth

Xavier Sal, Infested Captain

Intruder Alarm

Staff of Titania

Roaring Earth

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

This intricate loop relies on Xavier Sal, Infested Captain to feed on counters and continuously mint new Forest Dryad land creature tokens—fueled by Staff of Titania to spawn them initially and Roaring Earth to provide a steady stream of landfall triggers that drop +1/+1 counters onto your board. Every time a new Dryad arrives, Intruder Alarm triggers to untap all your creatures, letting you instantly reuse Xavier Sal's tap ability to do it all over again.
