Lotus Ring + Puresteel Paladin + Blaring Recruiter + Jinnie Fay, Jetmir's Second

Lotus Ring

Puresteel Paladin

Blaring Recruiter

Jinnie Fay, Jetmir's Second

How it works

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

This loop relies on transforming your mana into an endless parade of creatures, starting when you activate Blaring Recruiter's ability to generate a token with the help of Jinnie Fay, Jetmir's Second replacing it with a hasty cat. Once that token hits the board, Puresteel Paladin's metalcraft ability kicks in to reduce Lotus Ring's equip cost to zero, allowing you to instantly strap the artifact onto your new cat without spending any mana. You then cash in that equipped cat using Lotus Ring's sacrifice ability to recoup three white mana, which completely funds the next activation of Blaring Recruiter.
