Wight of the Reliquary + Retreat to Coralhelm + Emeria Angel

Wight of the Reliquary

Retreat to Coralhelm

Emeria Angel

How it works

1. Activate Wight of the Reliquary by tapping it and sacrificing another creature, causing you to search your library for a land card and put it onto the battlefield tapped.
2. When the land enters the battlefield, Emeria Angel and Retreat to Coralhelm trigger.
3. Resolve the Emeria Angel trigger, creating a 1/1 Bird creature token.
4. Resolve the Retreat to Coralhelm trigger, untapping Wight of the Reliquary.
5. Repeat.

This clever loop transforms a humble sacrifice into a steadily growing army and a completely cleared library. By using Wight of the Reliquary to trade a creature for a fresh land, you trigger both Emeria Angel to replace the sacrificed material with a flying Bird token and Retreat to Coralhelm to untap the Wight. Because Retreat to Coralhelm's landfall ability lets you untap the very creature you just used, you can repeat the process over and over until every single land from your deck is safely on the battlefield.
