The 4 combo pieces

What must be in place

You control at least four mana-producing lands except Dryad Arbor, two of which can tap to produce at least {B}

How to execute it

  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 {2}{B}{B} available and/or you control no other mana-producing lands.
  3. Cast Chthonian Nightmare by paying {1}{B}.
  4. When Chthonian Nightmare enters the battlefield, it triggers, causing you to get {E}{E}{E}.
  5. Activate Chthonian Nightmare by sacrificing World Shaper and returning Chthonian Nightmare from the battlefield to your hand, targeting Dryad Arbor.
  6. When World Shaper dies, its second ability triggers, returning all land cards from your graveyard to the battlefield tapped.
  7. The ability from step 3 fizzles due to having no legal target, as Dryad Arbor will be returned to the battlefield by World Shaper.
  8. Cast Chthonian Nightmare by paying {1}{B}.
  9. When Chthonian Nightmare enters the battlefield, it triggers, causing you to get {E}{E}{E}.
  10. Activate Chthonian Nightmare by paying {E}{E}{E}{E}, sacrificing Dryad Arbor and returning Chthonian Nightmare from the battlefield to your hand, returning World Shaper from your graveyard to the battlefield.
  11. Repeat.
