Mortuary + Grim Haruspex + Phyrexian Marauder

Mortuary

Grim Haruspex

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 Grim Haruspex.
3. Resolve the Mortuary trigger, putting Phyrexian Marauder from your graveyard onto the top of your library.
4. Resolve the Grim Haruspex trigger, causing you to draw a card, thus drawing Phyrexian Marauder from your library.
5. Repeat.

This ingenious loop turns a fragile artifact creature into an endless engine of card advantage and triggers. Because Phyrexian Marauder can be cast for zero mana with zero toughness, it instantly dies upon entering the battlefield as a state-based action. The moment it hits the graveyard, Mortuary intercepts it to place the Marauder right back on top of your library, while Grim Haruspex watches the creature die and immediately forces you to draw it. By cycling this zero-cost creature in and out of play, you generate an endless stream of enters-the-battlefield events, leaves-the-battlefield events, and death triggers to overwhelm your opponents.
