Lotus Ring + Puresteel Paladin + Ant Queen + Kratos, God of War

Lotus Ring

Puresteel Paladin

Ant Queen

Kratos, God of War

How it works

1. Activate Ant Queen by paying 1, creating a 1/1 Insect creature token.
2. Activate Lotus Ring's equip ability by paying 0 due to Puresteel Paladin, attaching it to the Insect.
3. Activate the Insect by tapping and sacrificing it, adding .
4. Repeat.
5. Once you have infinite mana, you may repeat step 1 as desired.

This clever engine turns green mana into an unstoppable swarm by leveraging Puresteel Paladin's metalcraft ability, which reduces the equip cost of Lotus Ring to zero once you have enough artifacts in play. With that free attachment ready, you use Ant Queen to spin out 1/1 Insect creature tokens, immediately equip them with Lotus Ring, and sacrifice them to the Ring's own mana ability to generate a net surplus of green mana. Though Kratos, God of War isn't directly involved in the infinite loop itself, his presence ensures that your endlessly generated tokens gain haste immediately to overwhelm any opponent.
