The 4 combo pieces

What must be in place

You can produce at least {3}{U}{B}{B} between sacrificing lands excluding Port of Karfell to Squandered Resources and/or by tapping those lands for mana.

How to execute it

  1. If desired, activate any number of other mana-producing lands you control by tapping them, adding at least {1} for each land tapped this way.
  2. Activate Squandered Resources by sacrificing a mana-producing land other than Port of Karfell, adding {U} or {B} if possible, or any other type of mana otherwise.
  3. Repeat step 2 until you control no other mana-producing lands except Port of Karfell.
  4. Activate Port of Karfell's second ability by paying {3}{U}{B}{B}, tapping and sacrificing it, causing you to mill four cards and return Lumra from your graveyard to the battlefield tapped.
  5. Lumra enters the battlefield and dies as a state-based action due to having 0 toughness.
  6. Lumra's enter-the-battlefield ability triggers, causing you to mill four cards and return all land cards from your graveyard to the battlefield untapped due to Archelos.
  7. Repeat.
