Intruder Alarm + Maskwood Nexus + Ensoul Artifact

Intruder Alarm

Maskwood Nexus

Ensoul Artifact

How it works

1. Activate any number of mana-producing creatures you control by tapping them, adding at least 3.
2. Activate Maskwood Nexus by paying 3 and tapping it, creating a 2/2 Shapeshifter creature token.
3. When the Shapeshifter enters the battlefield, Intruder Alarm triggers, untapping all creatures.
4. Repeat.
5. If creatures you control can tap to produce at least 4, this combo nets infinite mana.

This mesmerizing loop turns your ordinary mana dorks into an infinite token-generating engine, powered by the clever synergy of Maskwood Nexus and Intruder Alarm. Because Maskwood Nexus makes every creature you control every creature type, every new Shapeshifter token enters the battlefield as a creature that immediately triggers Intruder Alarm's global untap. As long as your creatures can produce enough mana to fund the {3} activation cost of Maskwood Nexus—or if you've used Ensoul Artifact to bring the Nexus itself into the fray as a 5/5 creature that can also untap—you can repeat this cycle endlessly. The result is an unbounded swarm of creatures, infinite entry triggers, and infinite mana from whatever your battlefield has to offer.
