Oltec Matterweaver + Ancestral Statue + Ashnod's Altar + Queen Allenal of Ruadach

Oltec Matterweaver

Ancestral Statue

Ashnod's Altar

Queen Allenal of Ruadach

How it works

1. Cast Ancestral Statue by paying 4
2. Oltec Matterweaver triggers, creating a 1/1 Soldier creature token and a 1/1 Gnome artifact creature token.
3. When Ancestral Statue enters the battlefield, it triggers, returning itself from the battlefield to your hand.
4. Activate Ashnod's Altar by sacrificing the Gnome and Soldier, adding CCCC.
5. Repeat.

This clever engine starts by casting Ancestral Statue, whose steep cost is easily offset by the mana we get back later. As you cast it, Oltec Matterweaver springs into action to generate a token, while Queen Allenal of Ruadach's replacement effect turns that single creation into an army by tagging along an extra Soldier token alongside the Gnome. Once Ancestral Statue hits the battlefield and its own trigger bounces it straight back to your hand, you simply feed those fresh tokens into Ashnod's Altar to generate the four colorless mana needed to recast the Statue, leaving you with infinite sacrifices, death triggers, and storm count.
