Mortuary + Moldervine Reclamation + Phyrexian Marauder

Mortuary

Moldervine Reclamation

Phyrexian Marauder

How it works

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

This ingenious loop turns a self-sacrificing artifact creature into a perpetual motion machine of card draw and life gain. By casting Phyrexian Marauder for zero mana, its zero toughness immediately sends it to the graveyard as a state-based action, making Mortuary's trigger place it right back on top of your library. Simultaneously, Moldervine Reclamation seizes upon that exact death to gain you 1 life and draw you a card, conveniently sliding the Marauder back into your hand so you can cast it all over again.
