Wylie Duke, Atiin Hero + Agatha's Soul Cauldron + Pili-Pala + Earthcraft

Wylie Duke, Atiin Hero

Agatha's Soul Cauldron

Pili-Pala

Earthcraft

How it works

1. Activate a basic land by tapping it, adding 1.
2. Activate Earthcraft by tapping Wylie Duke.
3. Wylie Duke triggers, causing you to draw a card and gain 1 life.
4. Resolve the Earthcraft ability, untapping a basic land.
5. Activate Wylie Duke using Pili-Pala's ability by paying 2 and untapping it, adding 1.
6. Repeat.

This ingenious loop relies on Agatha's Soul Cauldron to grant Pili-Pala's untap-and-mana-generation ability to Wylie Duke, Atiin Hero. With that activated ability on Wylie Duke, you can repeatedly tap him to Earthcraft—which untaps a basic land for mana—and then pay that mana to untap Wylie Duke using the Pili-Pala ability you bestowed upon him. Every single time you tap Wylie Duke for Earthcraft, his own triggered ability fires off, allowing you to cycle through your entire deck while gaining near-infinite life along the way.
