Agatha's Soul Cauldron + Kiki-Jiki, Mirror Breaker + Lurking Roper + Impassioned Orator

Agatha's Soul Cauldron

Kiki-Jiki, Mirror Breaker

Lurking Roper

Impassioned Orator

How it works

1. Activate Lurking Roper using Kiki-Jiki's ability by tapping it, creating a token copy of itself with haste.
2. When the Lurking Roper token enters the battlefield, Impassioned Orator triggers, causing you to gain 1 life.
3. Each Lurking Roper you control triggers, untapping themselves.
4. Repeat.
5. You may also target any nonlegendary creature you control.

This engine centers on feeding Kiki-Jiki, Mirror Breaker into Agatha's Soul Cauldron, granting its legendary copy-making activated ability to Lurking Roper. Because Lurking Roper untaps whenever you gain life, and Impassioned Orator ensures you gain 1 life every time a creature enters the battlefield, the resulting token copy of Lurking Roper immediately triggers its own untapping when it arrives. This creates a self-sustaining loop where you can endlessly tap the adapted Lurking Roper to churn out infinite hasty token copies of itself—or any other nonlegendary creature you control.
