Earthcraft + Wylie Duke, Atiin Hero + Pemmin's Aura

Earthcraft

Wylie Duke, Atiin Hero

Pemmin's Aura

How it works

1. Activate a basic Island by tapping it, adding .
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 Island.
5. Activate Pemmin's Aura's first ability by paying , untapping Wylie Duke.
6. Repeat.

This clever loop transforms Wylie Duke, Atiin Hero into an engine for infinite card draw and near-infinite life by keeping him in constant motion. Earthcraft allows you to tap Wylie Duke without attacking to untap a basic Island, which simultaneously triggers Wylie Duke's second ability to draw a card and gain 1 life. From there, you simply channel the blue mana generated by that basic Island back into Pemmin's Aura's untap ability, freeing Wylie Duke to be tapped all over again.
