Agatha's Soul Cauldron + Kiki-Jiki, Mirror Breaker + Captain of the Mists

Agatha's Soul Cauldron

Kiki-Jiki, Mirror Breaker

Captain of the Mists

How it works

1. Activate Captain of the Mists using Kiki-Jiki's ability by tapping it, creating a token copy of itself with haste.
2. When the Captain of the Mists token enters the battlefield, each other Captain of the Mists you cotnrol triggers, untapping themselves.
3. Repeat.
4. You may also target any nonlegendary Human you control.

By using Agatha's Soul Cauldron to exile Kiki-Jiki, Mirror Breaker and place a +1/+1 counter on Captain of the Mists, the Captain gains Kiki-Jiki’s iconic ability to duplicate creatures. Thanks to the Cauldron's passive mana-filtering, you can easily pay for the copied activation while leveraging Captain of the Mists' own triggered ability to untap itself whenever another Human enters the battlefield. This creates a self-sustaining loop where each token copy of the Captain untaps the original, letting you churn out an endless army of hasty duplicates.
