Emry, Lurker of the Loch + Displacer Kitten + Jeweled Lotus + Derevi, Empyrial Tactician

Emry, Lurker of the Loch

Displacer Kitten

Jeweled Lotus

Derevi, Empyrial Tactician

How it works

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

This clever loop turns the graveyard into an endless resource by leveraging Emry, Lurker of the Loch to repeatedly pull Jeweled Lotus back into play. Each time you recast the Lotus as a noncreature spell, Displacer Kitten triggers to blink Derevi, Empyrial Tactician, whose entry ability immediately untaps Emry and resets the whole engine. You can then sacrifice Jeweled Lotus for commander-restricted mana, repeating the sequence to generate infinite sacrifice triggers, enter-the-battlefield effects, and storm count.
