Mortuary + Walking Ballista + Gwenom, Remorseless

Mortuary

Walking Ballista

Gwenom, Remorseless

How it works

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

This clever loop relies on casting Walking Ballista for zero mana, allowing it to immediately enter the battlefield and hit the graveyard as a state-based action due to having zero toughness. Mortuary catches the dying construct and tucks it right back onto the top of your library, setting it up to be recast over and over. Meanwhile, Gwenom, Remorseless enables that top-deck casting and replaces the mana cost with a life payment—turning your life total into the fuel for an endless cascade of creature enters-the-battlefield, leaves-the-battlefield, and death triggers that can effortlessly rack up an infinite storm count.
