Squandered Resources + Aftermath Analyst + Chthonian Nightmare + The Necrobloom

Squandered Resources

Aftermath Analyst

Chthonian Nightmare

The Necrobloom

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, The Necrobloom 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 loop transforms a graveyard full of land cards into an engine of endless reanimation and mana by weaving together the sacrifice outlet Squandered Resources and the mass-return ability of Aftermath Analyst. As those lands flood back onto the battlefield, The Necrobloom amplifies every single entry with a landfall token while passively granting your graveyard lands dredge 2 to ensure your library is always well-stocked. Meanwhile, Chthonian Nightmare acts as the recursive glue, cycling endlessly between your hand and the battlefield by spending the energy it generates upon entry to resurrect the Analyst again and again.
