The Enigma Jewel // Locus of Enlightenment + Deserted Temple + Serra's Sanctum

The Enigma Jewel // Locus of Enlightenment

Deserted Temple

Serra's Sanctum

How it works

1. Activate Serra's Sanctum by tapping it, adding at least .
2. Activate Deserted Temple's second ability by paying 1 and tapping it, targeting itself.
3. Locus of Enlightenment triggers, copying Deserted Temple's ability, targeting Serra's Sanctum.
4. Resolve both Deserted Temple abilities, untapping it and Serra's Sanctum.
5. Repeat.

This brilliant engine transforms The Enigma Jewel into Locus of Enlightenment, granting it the activated abilities of every card exiled to craft it—specifically leveraging the land-untapping power of Deserted Temple. Because Locus of Enlightenment copies any non-mana activated ability you trigger, activating Deserted Temple to untap itself automatically triggers a copy that targets your Serra's Sanctum instead. This creates a self-sustaining loop that repeatedly untaps both lands, allowing Serra's Sanctum to yield an infinite amount of white mana.
