Emeria Shepherd + World Shaper + Blasting Station + Coastal Hornclaw

Emeria Shepherd

World Shaper

Blasting Station

Coastal Hornclaw

How it works

1. Activate Coastal Hornclaw by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Blasting Station by tapping it and 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. When World Shaper enters, Blasting Station triggers, untapping Blasting Station.
8. Resolve all remaining Emeria Shepherd triggers.
9. Resolve the Blasting Station ability from step 3.
10. Repeat

This clever loop puts World Shaper through an endless cycle of sacrifice and resurrection to unleash total devastation. First, you strip away your own lands using Coastal Hornclaw's activation cost, sending them straight to the graveyard. Then, Blasting Station steps in to sacrifice World Shaper, whose death trigger immediately returns every single one of those lands to the battlefield tapped. This massive influx of lands sparks Emeria Shepherd's landfall ability, which takes advantage of the Plains entering to not only pull World Shaper right back to the battlefield, but also recover any other nonland permanent cards from your graveyard. Finally, World Shaper's re-entry untaps Blasting Station, allowing you to deal infinite damage and repeat the whole sequence indefinitely.
