Mortuary + Ugin's Conjurant + Gwenom, Remorseless

Mortuary

Ugin's Conjurant

Gwenom, Remorseless

How it works

1. Cast Ugin's Conjurant either from your hand by paying 0 or from the top of your library by paying 0 life.
2. Ugin's Conjurant enters and dies as a state-based action due to having 0 toughness.
3. Mortuary triggers, putting Ugin's Conjurant from your graveyard onto the top of your library.
4. Repeat.

This clever loop turns the zero-cost restriction of Ugin's Conjurant into a relentless engine of creation and doom. Because Ugin's Conjurant enters the battlefield with no toughness when cast for free, it immediately heads to the graveyard, triggering Mortuary to seamlessly recycle it right back to the top of your library. Meanwhile, Gwenom, Remorseless capitalizes on this endless cycle by letting you look at and play cards from the top of your library, paying life instead of mana to recast Ugin's Conjurant over and over again.
