Mortuary + Haywire Mite + Yahenni, Undying Partisan + Gwenom, Remorseless

Mortuary

Haywire Mite

Yahenni, Undying Partisan

Gwenom, Remorseless

How it works

1. Activate Yahenni by sacrificing Haywire Mite.
2. When Haywire Mite dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Haywire Mite from your graveyard onto the top of your library.
4. Resolve the Haywire Mite trigger, causing you to gain 2 life
5. Resolve the Yahenni ability.
6. Cast Haywire Mite from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This elegant loop turns a simple bug into an endless engine of life and momentum. By using Yahenni, Undying Partisan to repeatedly sacrifice Haywire Mite, you trigger Mortuary to neatly recycle the Mite right back onto the top of your library. From there, Gwenom, Remorseless steps in to bypass normal casting restrictions, letting you replay the Mite straight off the top at the low cost of a single life point—which the Mite's own death trigger more than pays back.
