Emry, Lurker of the Loch + Displacer Kitten + Lotus Petal + Corridor Monitor

Emry, Lurker of the Loch

Displacer Kitten

Lotus Petal

Corridor Monitor

How it works

1. Activate Emry by tapping it, targeting Lotus Petal.
2. Cast Lotus Petal from your graveyard by paying 0.
3. Displacer Kitten triggers, blinking Corridor Monitor.
4. When Corridor Monitor enters, it triggers, untapping Emry.
5. Activate Lotus Petal by tapping and sacrificing it.
6. Repeat.

This engine spins into motion by leveraging Emry, Lurker of the Loch to repeatedly pull Lotus Petal out of your graveyard, casting it for zero mana to fuel Displacer Kitten's blink ability. Every time you cast that artifact, Displacer Kitten blinks Corridor Monitor, whose entrance trigger untaps Emry so the whole cycle can begin anew. Along the way, sacrificing Lotus Petal at each iteration yields an endless supply of colored mana, infinite storm count, and every possible artifact or creature trigger you could ever want.
