Emeria Shepherd + World Shaper + Woe Strider + Zuran Orb

Emeria Shepherd

World Shaper

Woe Strider

Zuran Orb

How it works

1. Activate Zuran Orb by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Woe Strider 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. Resolve the Woe Strider ability.
9. Repeat

This clever loop turns the steady sacrifice outlet of Woe Strider into an engine for total graveyard reclamation by constantly cycling your lands through Zuran Orb. When you sacrifice World Shaper to Woe Strider, World Shaper's death trigger sweeps every land back onto the battlefield at once, which in turn fires off a massive wave of Emeria Shepherd landfall triggers. Because those lands include Plains, Emeria Shepherd can instantly pluck World Shaper right back out of your graveyard and onto the battlefield, ready to be sacrificed all over again.
