Emry, Lurker of the Loch + Sewer-veillance Cam + Phantom Train

Emry, Lurker of the Loch

Sewer-veillance Cam

Phantom Train

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 Phantom Train by sacrificing Sewer-veillance Cam.
6. Sewer-veillance Cam triggers, untapping the mana-producing creature.
7. Resolve the Phantom Train ability.
8. Repeat.

This ingenious loop transforms a simple graveyard recursion engine into an explosive sequence by weaponizing Sewer-veillance Cam's enter-the-battlefield and leave-the-battlefield triggers. By casting Sewer-veillance Cam from your graveyard using Emry, Lurker of the Loch, you trigger its untap ability to ready Emry for the next iteration. Sacrificing Sewer-veillance Cam to Phantom Train not only grows your menacing Vehicle with a +1/+1 counter, but also triggers the Cam's leaving-the-battlefield ability to untap your mana source and keep the cycle spinning.
