Squandered Resources + Aftermath Analyst + Chthonian Nightmare + Eusocial Engineering

Squandered Resources

Aftermath Analyst

Chthonian Nightmare

Eusocial Engineering

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, Eusocial Engineering 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 intricate loop transforms a graveyard full of earth into an unstoppable engine by leveraging Squandered Resources to turn your entire land base into immediate mana. As you recast and replay Chthonian Nightmare, its energy replenishment fuels the resurrection of Aftermath Analyst, which continuously brings back all those sacrificed lands to feed the cycle anew. Every time these lands flood back onto the battlefield, Eusocial Engineering rewards your exponential growth by churning out an endless army of Robot tokens.
