Emry, Lurker of the Loch + Displacer Kitten + Lotus Petal + Flash Thompson, Spider-Fan

Emry, Lurker of the Loch

Displacer Kitten

Lotus Petal

Flash Thompson, Spider-Fan

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 Flash Thompson.
4. When Flash Thompson enters, it triggers, untapping Emry.
5. Activate Lotus Petal by tapping and sacrificing it.
6. Repeat.

This ingenious loop relies on Emry, Lurker of the Loch pulling Lotus Petal from your graveyard over and over again for free, fueled by the artifact's own sacrifice ability for mana. Every time you cast that artifact, Displacer Kitten's trigger blinks Flash Thompson, Spider-Fan back onto the battlefield. Flash Thompson's entry then untaps Emry, neatly resetting the merfolk so you can tap her again and repeat the entire cycle for an endless stream of mana and triggers.
