Mortuary + Moldervine Reclamation + Walking Ballista

Mortuary

Moldervine Reclamation

Walking Ballista

How it works

1. Cast Walking Ballista by paying 0.
2. Walking Ballista enters and dies as a state-based action due to having 0 toughness, triggering Mortuary and Moldervine Reclamation.
3. Resolve the Mortuary trigger, putting Walking Ballista from your graveyard onto the top of your library.
4. Resolve the Moldervine Reclamation trigger, causing you to draw a card, thus drawing Walking Ballista from your library, and gain 1 life.
5. Repeat.

This clever loop transforms a zero-mana creature into a self-sustaining engine of life and knowledge. When you cast Walking Ballista for zero, state-based actions send it straight to the graveyard, instantly awakening Mortuary to tuck the tiny automaton neatly back onto the top of your library. At the very same time, Moldervine Reclamation triggers from the death event, letting you draw that exact same Walking Ballista right back into your hand while padding your life total. By repeatedly casting and recycling your threat for zero mana, you can filter through your entire deck to assemble the rest of your win conditions.
