Yahenni, Undying Partisan + Agatha's Soul Cauldron + Walking Ballista

Yahenni, Undying Partisan
Agatha's Soul Cauldron
Walking Ballista

Requires
Yahenni, Undying Partisan must be on the battlefield. Agatha's Soul Cauldron must be on the battlefield. Walking Ballista must be in exile (exiled by Agatha's Soul Cauldron). Yahenni has at least one +1/+1 counter on it. You have a way to give Yahenni deathtouch.
Steps
  1. Give Yahenni deathtouch, if needed.
  2. Activate Yahenni using Walking Ballista's second ability by removing a +1/+1 counter from it, dealing 1 damage to a creature an opponent controls, and destroying it due to Yahenni's deathtouch.
  3. Yahenni triggers, putting a +1/+1 counter on it.
  4. Repeat from step 2 as desired.
  5. If you can give Yahenni deathtouch indefinitely, you may repeat this loop whenever a creature enters the battlefield under an opponent's control.
Results
Destroy all creatures opponents control. Destroy any creature that enters the battlefield under an opponent's control.
