The 2 combo pieces

How to execute it

  1. Activate Helm of Obedience by paying {1} and tapping it, causing target opponent to mill a card.
  2. Due to Leyline of the Void's replacement effect, the milled card is exiled instead of going to the graveyard, and that opponents repeats that process until their library is empty.
