How it works
Activate Gilraen by paying 2 and tapping it, blinking Auton Soldier. Choose to have Auton Soldier enter as a copy of Galadriel.
When Auton Soldier enters, Intruder Alarm and Galadriel trigger, adding and untapping all creatures.
Activate Gilraen by paying 2 and tapping it, blinking Galadriel.
When Galadriel enters, Intruder Alarm and Auton Soldier trigger, adding and untapping all creatures.
Repeat.
This clever loop achieves infinite green mana and creature enters-the-battlefield triggers by leveraging the blink engine of Gilraen, Dúnedain Protector alongside the continuous untap trigger of Intruder Alarm. By having Auton Soldier enter the battlefield as a nonlegendary copy of Galadriel, Light of Valinor, you double up on the alliance triggers that generate massive amounts of green mana every time a creature blinks. As you alternate using Gilraen to blink both Auton Soldier and the original Galadriel back and forth, Intruder Alarm untaps Gilraen on every single entry to keep the cycle spinning infinitely.
