Emry, Lurker of the Loch
Dross Scorpion
Mycosynth Lattice
Walking Ballista

Requires
Emry, Lurker of the Loch must be on the battlefield. Dross Scorpion must be on the battlefield. Mycosynth Lattice must be on the battlefield. Walking Ballista must be in the graveyard. Emry does not have summoning sickness.
Steps
  1. Activate Emry by tapping it, allowing you to cast Walking Ballista from your graveyard this turn.
  2. Cast Walking Ballista by paying 0.
  3. Walking Ballista enters the battlefield and dies as a state-based action due to having zero toughness.
  4. Dross Scorpion triggers, untapping Emry.
  5. Repeat.
Results
Infinite death triggers. Infinite ETB. Infinite LTB. Infinite storm count.
