Mortuary + Ranger Class + Ugin's Conjurant

Mortuary

Ranger Class

Ugin's Conjurant

How it works

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

This loop turns a zero-mana investment into an endless recycling engine by exploiting Ugin's Conjurant entering with zero toughness when cast for {0}. As the creature immediately hits the graveyard, Mortuary catches it and places it right back on top of your library. Meanwhile, Ranger Class provides the crucial top-deck infrastructure with its Level 3 ability, letting you continuously recast Ugin's Conjurant directly from the library to fuel infinite enters-the-battlefield triggers, death triggers, and storm count.
