Lotus Ring + Puresteel Paladin + Jade Mage + Kratos, God of War

Lotus Ring

Puresteel Paladin

Jade Mage

Kratos, God of War

How it works

1. Activate Jade Mage by paying 2, creating a 1/1 Saproling creature token.
2. Activate Lotus Ring's equip ability by paying 0 due to Puresteel Paladin, attaching it to the Saproling.
3. Activate the Saproling by tapping and sacrificing it, adding .
4. Repeat.

This clever loop lets you turn green mana into a self-sustaining engine by abusing cost-reduction mechanics. With Puresteel Paladin on the battlefield providing metalcraft, the equip cost of Lotus Ring becomes completely free, allowing you to instantly strap the artifact to whatever target you choose. You then use Jade Mage to churn out fodder, attach the ring, and sacrifice the token for mana to fund the next token creation. Meanwhile, Kratos, God of War and the rest of your board benefit from free creature entries and sacrifices, even if Kratos's end-step damage is mostly a sideshow to your infinite loop.
