Lotus Ring + Puresteel Paladin + Luminarch Ascension + Fervor

Lotus Ring

Puresteel Paladin

Luminarch Ascension

Fervor

How it works

1. Activate Luminarch Ascension by paying 1, creating a 4/4 Angel creature token.
2. Activate Lotus Ring's equip ability by paying 0 due to Puresteel Paladin, attaching it to the Angel.
3. Activate the Angel by tapping and sacrificing it, adding .
4. Repeat.
5. Once you have infinite mana, you may forego sacrificing the Angels.

This clever mana engine transforms a modest enchantment into a relentless angelic factory. With Puresteel Paladin's metalcraft reducing equip costs to zero, Lotus Ring can instantly latch onto any newcomer without wasting precious mana. Luminarch Ascension supplies the raw material by pumping out Angel tokens that gain immediate haste thanks to Fervor, allowing them to tap and sacrifice themselves right away to Lotus Ring for a net profit of mana to feed the loop anew.
