Mortuary + Weatherlight Compleated + Phyrexian Marauder

Mortuary

Weatherlight Compleated

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 Weatherlight Compleated.
3. Resolve the Mortuary trigger, putting Phyrexian Marauder from your graveyard onto the top of your library.
4. Resolve the Weatherlight Compleated trigger, causing you to put a phyresis counter on it and draw a card, thus drawing Omarthis from your library.
5. Repeat.

This delightfully morbid loop relies on Phyrexian Marauder entering the battlefield with zero toughness, instantly dying as a state-based action to trigger a cascade of benefits without ever needing to spend mana. Mortuary catches the Marauder as it hits the graveyard, neatly tucking it back onto the top of your library so you can draw it right back. Meanwhile, Weatherlight Compleated acts as the engine's watchful eye, accumulating phyresis counters off every single death and turning those repeated triggers into a steady stream of card draw.
