Requires
Reaper King must be on the battlefield. Kozilek, Butcher of Truth must be on the battlefield, or in the library. Atla Palani, Nest Tender must be on the battlefield. Maskwood Nexus must be on the battlefield. You have a way to cause a creature to enter the battlefield under your control.
Steps

  2. When that creature enters the battlefield, Reaper King triggers, destroying that creature.
  3. Resolve Atla Palani's trigger, revealing cards from the top of your library until you reveal a creature card and putting it onto the battlefield.
  4. Repeat from step 2 until Kozilek enters the battlefield then dies, or until you choose to end the loop by destroying an opponent's permanent.
  5. If Kozilek dies, it and Atla Palani trigger.
  6. Resolve Kozilek's trigger, shuffling your graveyard into your library.
  7. Continue from step 3.
Results
Infinite death triggers. Infinite ETB. Infinite LTB. Put all creatures from your library onto the battlefield, then they die, then repeat infinitely.
