How it works

1. At the beginning of your upkeep, Panoptic Mirror triggers.
2. Holding priority, activate Temple of the False God by tapping it, adding CC.
3. Activate Strionic Resonator 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 Temple of the False God and Strionic Resonator.
6. Repeat from step 2.
