Basal Sliver + Enduring Renewal + Metallic Sliver

Basal Sliver

Enduring Renewal

Metallic Sliver

How it works

1. Sacrifice Metallic Sliver to its ability, adding .
2. Enduring Renewal triggers, returning Metallic Sliver from your graveyard to your hand.
3. Cast Metallic Sliver.
4. Repeat.

This loop relies on transforming a cheap, unassuming artifact creature into a renewable energy source, fueled entirely by the shared hive-mind mechanics of Basal Sliver. By turning Metallic Sliver into a mana-generating sacrifice outlet through the Sliver's granted ability, you immediately trigger Enduring Renewal to bypass the graveyard and bounce the artifact right back to your hand. Because Enduring Renewal instantly returns creatures dying from the battlefield straight to your hand, recast Metallic Sliver for zero mana and repeat the cycle to generate infinite black mana along with an endless storm count.
