Emry, Lurker of the Loch

Sewer-veillance Cam

Arcbound Ravager

How it works

1. Activate Emry by tapping it, allowing you to cast Sewer-veillance Cam from your graveyard this turn.
2. Activate a creature by tapping it, adding at least .
3. Cast Sewer-veillance Cam from your graveyard by paying .
4. When Sewer-veillance Cam enters, it triggers, untapping Emry.
5. Activate Arcbound Ravager by sacrificing Sewer-veillance Cam.
6. Sewer-veillance Cam triggers, untapping the mana-producing creature.
7. Resolve the Arcbound Ravager ability.
8. Repeat.

This intricate loop turns Emry, Lurker of the Loch into a relentless graveyard-casting engine, using her tap ability to continually pull Sewer-veillance Cam back from the dead for a single mana. Every time Sewer-veillance Cam enters or leaves the battlefield, its clever trigger untaps both Emry and your mana-producing creature, creating a self-sustaining cycle of untaps. Arcbound Ravager acts as the crucial sacrifice outlet that triggers the cam's leave-the-battlefield ability while growing steadily larger with a cascade of +1/+1 counters.
