Cogwork Assembler + Esika's Chariot + Ashnod's Altar + Parallel Lives

Cogwork Assembler

Esika's Chariot

Ashnod's Altar

Parallel Lives

How it works

1. Activate Cogwork Assembler by paying 7, creating two token copies of Esika's Chariot.
2. When the Esika's Chariots enter the battlefield, their first abilities trigger, creating four 2/2 Cat creature tokens.
3. Activate Ashnod's Altar four times by sacrificing the Cats, adding eight C.
4. Repeat.
5. Once you have infinite mana, you may forego sacrificing the Cats and/or target any other artifact using Cogwork Assembler.

This explosive loop starts by sinking seven mana into Cogwork Assembler to target Esika's Chariot, whose entry triggers are immediately amplified by Parallel Lives to flood the board with Cat tokens. Ashnod's Altar then provides the necessary mana engine by turning those disposable creatures into a surplus of colorless mana, which funds the next activation of the Assembler. Because Parallel Lives doubles every token created along the way, you easily outpace the mana cost, leaving you with an unstoppable army of copies, cats, and infinite mana.
