The 3 combo pieces

What must be in place

Infinite Reflection attached to Dauthi Voidwalker.
You control at least one additional nontoken creature.
An opponent has a creature card in exile with a void counter on it.

How to execute it

  1. Activate a Dauthi Voidwalker that does not have Infinite Reflection attached by tapping and sacrificing it.
  2. If the creature was owned by an opponent, it is exiled with a void counter instead of being put into its owner's graveyard.
  3. Resolve the Dauthi Voidwalker ability, causing you to cast a creature card from an opponent's exile without paying its mana cost.
  4. The creature enters the battlefield as a copy of Dauthi Voidwalker due to Infinite Reflection.
  5. Repeat.
