Pulmonic Sliver + Basal Sliver + Augur of Autumn

Pulmonic Sliver

Basal Sliver

Augur of Autumn

How it works

1. Activate the Sliver that can be cast using by sacrificing it, adding .
2. The Sliver is put onto the top of your library instead of into your graveyard due to the replacement effect given to it by Pulmonic Sliver.
3. Cast the Sliver from the top of your library by paying its mana cost.
4. Repeat.

This elegant loop turns your entire Sliver hive into a self-sustaining engine by stacking continuous replacement effects with top-deck casting. Basal Sliver provides the sacrifice outlet to generate black mana, while Pulmonic Sliver steps in to rewrite fate, ensuring that every fallen Sliver bypasses the graveyard to sit right on top of your library instead. To tie the room together, Augur of Autumn lets you peer into the future and continuously cast those creatures straight from the top of your library, fueling an infinite loop of entry and exit triggers as well as a storm count that can easily close out the game.
