Agatha's Soul Cauldron
Walking Ballista
Evernight Shade

Requires
Agatha's Soul Cauldron must be on the battlefield. Walking Ballista must be in exile (exiled by Agatha's Soul Cauldron). Evernight Shade must be on the battlefield. Evernight Shade has at least one +1/+1 counter on it.
Steps
  1. Activate Evernight Shade using Walking Ballista's second ability by removing a +1/+1 counter from it.
  2. Repeat step 1 until Evernight Shade has no +1/+1 counters on it.
  3. Resolve all Evernight Shade abilities dealing 1 damage to Evernight Shade, and any remaining damage to any target(s).
  4. Evernight Shade dies as a state-based action due to having 0 toughness.
  5. Evernight Shade's undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
  6. Repeat.
Results
Infinite death triggers. Infinite ETB. Infinite LTB.
