Xavier Sal, Infested Captain + Intruder Alarm + Awaken the Woods + Khalni Heart Expedition

Xavier Sal, Infested Captain

Intruder Alarm

Awaken the Woods

Khalni Heart Expedition

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

This ingenious loop turns a modest forest into an endless march of nature, fueled by Xavier Sal, Infested Captain using his tap ability to strip a counter from Khalni Heart Expedition in order to populate another Forest Dryad token via Awaken the Woods. Every single time a new Dryad hits the battlefield, Intruder Alarm triggers to untap all your creatures—including Xavier Sal—allowing you to immediately tap him again, while Khalni Heart Expedition quietly racks up quest counters off the resulting landfall triggers to eventually help fetch your remaining basics. Because Xavier Sal's token generation keeps restarting the untap cycle, you can repeat this process as many times as you like to amass infinite creature tokens, infinite ETB triggers, and infinite mana from any mana-producing creatures you control.
