Lotus Ring + Puresteel Paladin + Blaring Recruiter + Maelstrom Wanderer

Lotus Ring

Puresteel Paladin

Blaring Recruiter

Maelstrom Wanderer

How it works

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

This loop relies on Puresteel Paladin's metalcraft ability to drop Lotus Ring's equip cost down to zero, turning any creature into a recyclable engine. By activating Blaring Recruiter for {2}{W}, you continuously churn out 1/1 Warrior creature tokens that can instantly pick up Lotus Ring for free and immediately sacrifice themselves to tap for three white mana—yielding a net positive mana return to sustain the loop indefinitely. While Maelstrom Wanderer isn't directly tapped or sacrificed in the execution of the loop, its presence brilliantly grants haste to every token the moment they enter the battlefield, ensuring your newly generated army is ready to act the second they hit play.
