Panoptic Mirror

Lithoform Engine

Ghostly Flicker

Ur-Golem's Eye

How it works

1. At the beginning of your upkeep, Panoptic Mirror triggers.
2. Holding priority, activate Ur-Golem's Eye by tapping it, adding CC.
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 Ur-Golem's Eye and Lithoform Engine.
6. Repeat from step 2.
