The Enigma Jewel // Locus of Enlightenment + Deserted Temple + Matzalantli, the Great Door // The Core

The Enigma Jewel // Locus of Enlightenment

Deserted Temple

Matzalantli, the Great Door // The Core

How it works

1. Activate The Core by tapping it, adding at least two mana of any color.
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 The Core.
4. Resolve both Deserted Temple abilities, untapping it and The Core.
5. Repeat.

This ingenious engine transforms The Enigma Jewel into Locus of Enlightenment, setting the stage for an explosive copying loop once you manage to flip Matzalantli, the Great Door into The Core. Because Locus of Enlightenment copies any non-mana ability you activate, tapping Deserted Temple to untap itself doesn't just ready your land—it triggers a mirrored untap targeting The Core. With The Core yielding massive amounts of mana based on your graveyard's contents, this reciprocal cycle of untapping allows you to continually net color-matched treasures while feeding Deserted Temple's activation cost.
