Squandered Resources + Aftermath Analyst + Chthonian Nightmare + Zendikar's Roil

Squandered Resources

Aftermath Analyst

Chthonian Nightmare

Zendikar's Roil

How it works

1. Activate Squandered Resources by sacrificing a land, adding one mana of any color that land could produce.
2. Repeat step 1 until you have at least 4 available and/or you control no other mana-producing lands.
3. Activate Aftermath Analyst by paying 3 and sacrificing it, returning all land cards from your graveyard to the battlefield tapped.
4. When the lands enter the battlefield, Zendikar's Roil triggers that many times, creating that many creature tokens.
5. Activate Chthonian Nightmare by paying EE, sacrificing a creature and returning Chthonian Nightmare from the battlefield to your hand, returning Aftermath Analyst from your graveyard to the battlefield.
6. When Aftermath Analyst enters the battlefield, it triggers, causing you to mill three cards.
7. Cast Chthonian Nightmare by paying 1.
8. When Chthonian Nightmare enters the battlefield, it triggers, causing you to get EEE.
9. Repeat.

This delightful loop lets you recycle your entire land base into an endless engine of creation and recursion. By using Squandered Resources to turn your lands into raw mana, you fuel Aftermath Analyst's ability to flood the battlefield with those same lands from your graveyard. Every single land that returns triggers Zendikar's Roil, minting an army of Elemental tokens to feed directly into Chthonian Nightmare. That enchantment's self-bouncing ability lets you trade those tokens and reuse its energy to bring Aftermath Analyst back over and over again, generating infinite resources along the way.
