Shifting Woodland + Aftermath Analyst + Thaumatog + Archelos, Lagoon Mystic

Shifting Woodland

Aftermath Analyst

Thaumatog

Archelos, Lagoon Mystic

How it works

1. Activate Thaumatog by sacrificing any land except Shifting Woodland.
2. Repeat step 1 until you control no other lands except Shifting Woodland.
3. Activate Shifting Woodland's second ability by paying 2, causing it to become a copy of Aftermath Analyst until end of turn.
4. Activate Shifting Woodland by paying 3 and sacrificing it, returning it and all other land cards from your graveyard to the battlefield untapped due to Arcehlos.
5. Activate any number of lands by tapping them, adding at least 5.
6. Repeat.

This clever loop turns your graveyard into a self-sustaining engine by utilizing Thaumatog to clear away excess lands until only Shifting Woodland remains, allowing it to safely copy Aftermath Analyst's sacrifice ability with delirium active. Because Archelos, Lagoon Mystic is kept untapped, every single land returned to the field enters completely untapped instead of tapped, instantly refreshing your mana supply for the next iteration. With the mana generated by tapping your lands, you can endlessly repeat the process to fuel infinite sacrifices and landfall triggers.
