This clever loop relies on Phyrexian Marauder entering the battlefield with zero toughness for zero mana, letting it immediately perish as a state-based action to fuel Mortuary and trigger its graveyard-to-library redirection. Mortuary handles the heavy lifting of recycling the creature straight to the top of your library, perfectly setting up Amareth, the Lustrous to trigger off the artifact creature's arrival and draw it right back into your hand. Because Phyrexian Marauder shares the artifact type with itself when it re-enters, Amareth effortlessly nets you the card every single iteration, creating a self-sustaining engine for infinite storm count and creature triggers.
