Emeria Shepherd + World Shaper + Shilgengar, Sire of Famine + Sylvan Safekeeper

Emeria Shepherd

World Shaper

Shilgengar, Sire of Famine

Sylvan Safekeeper

How it works

1. Activate Sylvan Safekeeper by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Shilgengar 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 Shilgengar ability.
9. Repeat
10. Resolve all Sylvan Safekeeper abilities.

This intricate loop begins by using Sylvan Safekeeper to systematically sacrifice every land you control, dumping them straight into the graveyard while fueling any graveyard-filling you might need. Once your lands are binned, Shilgengar, Sire of Famine provides the necessary sacrifice outlet to send World Shaper to the graveyard, triggering its death ability to flood the battlefield with all those lands at once. Those arriving lands immediately awaken Emeria Shepherd's landfall ability, letting you effortlessly pluck World Shaper right back out of the graveyard and repeat the cycle for infinite sacrificial value and astronomical token generation.
