Mortuary + Vivien, Monsters' Advocate + Walking Ballista

Mortuary

Vivien, Monsters' Advocate

Walking Ballista

How it works

1. Cast Walking Ballista either from your hand or from the top of your library by paying 0.
2. Walking Ballista enters the battlefield and dies as a state-based action due to having zero toughness.
3. Mortuary triggers, putting Walking Ballista on top of your library from your graveyard.
4. Repeat.

This clever loop relies on casting Walking Ballista for zero mana, allowing it to immediately head to the graveyard as a state-based action due to having zero toughness. Mortuary catches the dying automaton every single time, neatly placing it back on top of your library instead of letting it rest. Meanwhile, Vivien, Monsters' Advocate provides the crucial top-deck perspective and permission you need to keep replaying the 0-mana artifact over and over again. By cycling Walking Ballista through this endless loop, you rack up an infinite storm count alongside limitless creature enters-the-battlefield and leaves-the-battlefield triggers.
