Mortuary + Weatherlight Compleated + Cryptic Trilobite

Mortuary

Weatherlight Compleated

Cryptic Trilobite

How it works

1. Cast Cryptic Trilobite by paying 0.
2. Cryptic Trilobite enters and dies as a state-based action due to having 0 toughness, triggering Mortuary and Weatherlight Compleated.
3. Resolve the Mortuary trigger, putting Cryptic Trilobite 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.
