Mortuary + Moldervine Reclamation + Ugin's Conjurant

Mortuary

Moldervine Reclamation

Ugin's Conjurant

How it works

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

This elegant loop turns Ugin's Conjurant into a self-recycling engine simply by casting it for zero mana, allowing state-based actions to send it straight to the graveyard. As it hits the bin, Mortuary catches it on the way down to tuck it right back onto the top of your library, while Moldervine Reclamation rewards you for the creature's demise by letting you draw it right back into your hand alongside a steady stream of life. Because Ugin's Conjurant has no mana cost and enters with zero toughness, you can repeat this process endlessly to fuel an infinite storm count, endless life, and a never-ending parade of enter-the-battlefield and death triggers.
