Horizon Explorer

How it works

1. Play Lotus Field. When it enters untapped due to Horizon Explorer, 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 Horizon Explorer. 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 Horizon Explorer. Choose to have Echoing Deeps enter as a copy of Lotus Field.
11. Repeat from step 5.

This intricate loop harnesses the explosive mana production of Lotus Field alongside Echoing Deeps, which cleverly enters the graveyard ready to copy that exact same powerful land. To make the cycle self-sustaining, Horizon Explorer ensures every returning land enters untapped, providing the necessary staging ground for your resources. Meanwhile, Aftermath Analyst and Shifting Woodland share the heavy lifting of recursion, allowing you to repeatedly sacrifice and dredge your lands right back to the battlefield to continually feed your mana supply.
