Yenna, Redtooth Regent + Ordeal of Nylea + Tiller Engine + Faith Healer

Yenna, Redtooth Regent

Ordeal of Nylea

Tiller Engine

Faith Healer

How it works

1. Activate Yenna by paying 2 and tapping it, creating a token copy of Ordeal of Nylea, then untapping Yenna and causing you to scry 2.
2. Activate Faith Healer by sacrificing the Ordeal of Nylea token.
3. The Ordeal of Nylea token's second ability triggers, causing you to search your library for two basic land cards and put them onto the battlefield tapped.
4. When the lands enter the battlefield, Tiller Engine triggers twice, untapping them.
5. Resolve the Faith Healer ability from step 2, causing you to gain 2 life.
6. Activate the two lands by tapping them, adding 2.
7. Repeat.

This clever loop turns Yenna, Redtooth Regent into an infinite enchantment-copying engine by utilizing her unique ability to duplicate Ordeal of Nylea without restriction. Once the token copy enters the battlefield, Faith Healer steps in to cleanly sacrifice it, instantly triggering the Ordeal's search ability to pull two basic lands straight from your library. Because those lands enter the battlefield tapped, Tiller Engine triggers to immediately untap them, refunding your mana investment and letting you tap them to pay for Yenna's activation all over again.
