Emeria Shepherd + World Shaper + Lithatog + Phantom Train

Emeria Shepherd

World Shaper

Lithatog

Phantom Train

How it works

1. Activate Lithatog by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Phantom Train 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 Phantom Train ability.
9. Repeat

This clever loop turns the cycle of land sacrifice and return into an engine for infinite value, anchored by Emeria Shepherd's brilliant landfall trigger when a Plains enters. Lithatog clears the way by feeding your lands to the graveyard, while Phantom Train steps in to repeatedly sacrifice World Shaper. Every time World Shaper dies, its triggered ability rushes every land back to the battlefield tapped, triggering Emeria Shepherd to not only fish World Shaper right back out of the graveyard, but also recur any other nonland permanent you desire.
