Agatha's Soul Cauldron + Kiki-Jiki, Mirror Breaker + Brimstone Trebuchet

Agatha's Soul Cauldron

Kiki-Jiki, Mirror Breaker

Brimstone Trebuchet

How it works

1. Activate Brimstone Trebuchet using Kiki-Jiki's ability by tapping it, creating a token copy of any nonlegendary Knight you control with haste.
2. When the Knight token enters the battlefield, Brimstone Trebuchet triggers, untapping itself.
3. Repeat.

This clever loop turns your battlefield into a relentless artillery range by feeding Kiki-Jiki, Mirror Breaker's activated ability into Brimstone Trebuchet via Agatha's Soul Cauldron. With the Cauldron exiling Kiki-Jiki and granting its tap ability to any creature bearing a +1/+1 counter, your Brimstone Trebuchet can suddenly start tapping to create hasty token copies of whatever nonlegendary Knight you control. Every time that Knight token enters the battlefield, the Trebuchet's own triggered ability untaps it, letting you repeat the process to blast your opponents for infinite damage while churning out an endless army of hasty tokens.
