How it works
Activate Emry by tapping it, targeting Jeweled Lotus.
Cast Jeweled Lotus from your graveyard by paying 0.
When Sparring Mummy enters, it triggers, untapping Emry.
Activate Jeweled Lotus by tapping and sacrificing it.
Repeat.
This engine turns the recycling power of Emry, Lurker of the Loch into a self-sustaining loop by leveraging Jeweled Lotus as a recurring zero-mana artifact. Every time you recast the Lotus, Displacer Kitten triggers to blink Sparring Mummy, whose entry ability neatly untaps Emry so she can immediately target the Lotus in the graveyard all over again. Meanwhile, the mana generated by sacrificing Jeweled Lotus fuels the casting costs while creating an endless stream of artifact and creature triggers.
