Patrol Signaler + Paradise Mantle + Intruder Alarm

Patrol Signaler

Paradise Mantle

Intruder Alarm

How it works

1. Activate Patrol Signaler by tapping it, adding .
2. Activate Patrol Signaler by paying 1 and untapping it, creating a 1/1 Kithkin Soldier creature token.
3. When the Kithkin Soldier enters the battlefield, Intruder Alarm triggers.
4. Holding priority, activate Patrol Signaler by tapping it, adding .
5. Resolve the Intruder Alarm trigger, untapping all creatures.
6. Repeat.

This clever loop turns Patrol Signaler into a one-creature token factory by letting it fund its own activation cost. By equipping Paradise Mantle to Patrol Signaler, it gains the ability to tap for mana, which pays the white mana requirement of its untap ability while Intruder Alarm ensures every newly minted Kithkin Soldier immediately untaps the board upon entering the battlefield. Every cycle generates a net positive of mana and an army of creatures, perfectly exploiting Intruder Alarm's global untap trigger to keep the chain reacting infinitely.
