Emeria Shepherd + World Shaper + Thaumatog + Thermopod

Emeria Shepherd

World Shaper

Thaumatog

Thermopod

How it works

1. Activate Thaumatog by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Thermopod 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 clever engine transforms the cycle of life and death into a self-sustaining loop powered by Thermopod's ability to turn sacrificed creatures into red mana. You begin by using Thaumatog to clear away your lands, feeding them to the grave so that World Shaper can eventually follow them by leaping into Thermopod's maw. When World Shaper dies, its triggered ability floods the battlefield with all those departed lands at once, which in turn awakens Emeria Shepherd's landfall triggers. Because those lands include Plains, Emeria Shepherd plucks World Shaper right back from the graveyard to repeat the cycle infinitely, while also recycling any other nonland permanents you desire.
