Emeria Shepherd + World Shaper + Phyrexian Altar + Coastal Hornclaw

Emeria Shepherd

World Shaper

Phyrexian Altar

Coastal Hornclaw

How it works

1. Activate Coastal Hornclaw by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Phyrexian Altar by sacrificing World Shaper.
4. When World Shaper dies, it triggers, return all lands from your graveyard to the battlefield tapped.
5. When the lands enter, Emeria Shepherd triggers that many times.
6. Resolve an Emeria Shepherd trigger that was triggered by a Plains, returning World Shaper from your graveyard to the battlefield.
7. Resolve all remaining Emeria Shepherd triggers.
8. Repeat

This elegant loop transforms the humble sacrifice outlet of Phyrexian Altar and the self-destructive activation of Coastal Hornclaw into a relentless engine of resurrection. By intentionally sending your lands to the graveyard through Coastal Hornclaw, you set the stage for World Shaper to hit the altar and trigger its own death ability, flooding the battlefield with your fallen lands all at once. Each of those returning lands fuels Emeria Shepherd's landfall ability, letting you effortlessly pluck World Shaper right back out of the graveyard to restart the cycle while generating an endless supply of colored mana and triggering every death, sacrifice, and entry effect you could ever desire.
