Panoptic Mirror + Lithoform Engine + Ghostly Flicker + The Great Henge

Panoptic Mirror

Lithoform Engine

Ghostly Flicker

The Great Henge

How it works

1. At the beginning of your upkeep, Panoptic Mirror triggers.
2. Holding priority, activate The Great Henge by tapping it, adding and causing you to gain 2 life.
3. Activate Lithoform Engine's first ability by paying 2 and tapping it, copying Panoptic Mirror's trigger.
4. Resolve the copy of Panoptic Mirror's trigger, casting a copy of Ghostly Flicker without paying its mana cost.
5. Resolve the copy of Ghostly Flicker, blinking The Great Henge and Lithoform Engine.
6. Repeat from step 2.

This clever loop turns Panoptic Mirror into an engine of endless repetition by having it perpetually cast Ghostly Flicker for free off its upkeep trigger. To make this self-sustaining, Lithoform Engine steps in to copy that very trigger so you can generate multiple spells from a single turn, while The Great Henge provides the crucial green mana and life buffer needed to fund the engine's activation costs. Because Ghostly Flicker continually blinks both artifacts, you reset them to be tapped and used again, letting you cycle through the entire sequence indefinitely for boundless storm and lifegain triggers.
