Lotus Field + Echoing Deeps + Aftermath Analyst + Shifting Woodland + Spelunking

Lotus Field

Echoing Deeps

Aftermath Analyst

Shifting Woodland

Spelunking

How it works

1. Play Lotus Field. When it enters untapped due to Spelunking, it triggers.
2. Holding priority, activate Lotus Field by tapping it, adding .
3. Resolve the Lotus Field trigger, sacrificing it and Echoing Deeps.
4. Activate Aftermath Analyst by paying 3 and sacrificing it, returning all land cards from your graveyard to the battlefield untapped due to Spelunking. Choose to have Echoing Deeps enter as a copy of Lotus Field.
5. When Echoing Deeps and Lotus Field enter, they each trigger.
6. Holding priority, activate Echoing Deeps, Lotus Field and two other mana-producing lands except Shifting Woodland by tapping them, adding at least 5.
7. Resolve the Echoing Deeps and Lotus Field triggers, sacrificing them and the lands tapped for mana in step 6.
8. Activate Shifting Woodland's first ability by tapping it, adding .
9. Activate Shifting Woodland's second ability by paying 2, causing it to become a copy of Aftermath Analyst.
10. Activate Shifting Woodland by paying 3 and sacrificing it, returning all land cards from your graveyard to the battlefield untapped due to Spelunking. Choose to have Echoing Deeps enter as a copy of Lotus Field.
11. Repeat from step 5.

This elegant loop relies on Spelunking to rewrite the rules of engagement, ensuring that Lotus Field and its imitators skip their usual penalty and enter the battlefield completely untapped. Once Lotus Field hits the graveyard, Echoing Deeps seamlessly steps into its shoes by entering as an exact copy of the hexproof powerhouse, all while Aftermath Analyst sits ready to unearth your entire land base from the graveyard. The real genius, however, is Shifting Woodland: once delirium is achieved, this land can temporarily transform into a copy of Aftermath Analyst itself, letting you repeat the sacrifice-and-return cycle indefinitely to generate boundless mana and landfall triggers.
