Panoptic Mirror + Lithoform Engine + Ghostly Flicker + Mana Crypt

Panoptic Mirror

Lithoform Engine

Ghostly Flicker

Mana Crypt

How it works

1. At the beginning of your upkeep, Panoptic Mirror triggers.
2. Holding priority, activate Mana Crypt 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 Mana Crypt and Lithoform Engine.
6. Repeat from step 2.
