Xavier Sal, Infested Captain + Intruder Alarm + Staff of Titania + Fearless Fledgling

Xavier Sal, Infested Captain

Intruder Alarm

Staff of Titania

Fearless Fledgling

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

This ingenious engine spins up an infinite loop by leveraging Xavier Sal, Infested Captain to duplicate tokens, feeding a continuous cycle of untaps from Intruder Alarm. Every time Xavier populates a Forest Dryad—originally sparked by attacking with a creature equipped with Staff of Titania—the new Dryad's arrival triggers Intruder Alarm to untap your board, allowing Xavier to tap and repeat the process. Meanwhile, Fearless Fledgling grows larger with every iteration by soaking up the landfall triggers generated by each new Dryad, turning a simple populate loop into an overwhelming army of flying threats.
