Mortuary + Chamber Sentry + Weatherlight Compleated

Mortuary

Chamber Sentry

Weatherlight Compleated

How it works

1. Cast Chamber Sentry by paying 0.
2. Chamber Sentry enters and dies as a state-based action due to having 0 toughness, triggering Mortuary and Weatherlight Compleated.
3. Resolve the Mortuary trigger, putting Chamber Sentry 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 ingenious loop turns the fragile nature of a zero-mana creature into an endless engine of card advantage and triggers. By casting Chamber Sentry for zero, state-based actions immediately send it to the graveyard, which triggers Mortuary to seamlessly recycle it right back to the top of your library. At the same time, Weatherlight Compleated watches each of these deaths to accumulate phyresis counters, allowing you to steadily scry and draw through your deck every single iteration.
