Lotus Ring + Puresteel Paladin + Marneus Calgar + Maelstrom Wanderer

Lotus Ring

Puresteel Paladin

Marneus Calgar

Maelstrom Wanderer

How it works

1. Activate Marneus Calgar by paying 6, creating two 2/2 Astartes Warrior creature tokens.
2. When the Astartes Warriors enter the battlefield, Marneus Calgar triggers, causing you to draw a card.
3. Activate Lotus Ring's equip ability by paying 0 due to Puresteel Paladin, attaching it to an Astartes Warrior.
4. Activate the Astartes Warrior with Lotus Ring attached by tapping and sacrificing it, adding 3.
5. Repeat from step 3 for the remaining Astartes Warrior.
6. Repeat from step 1.

This ingenious loop turns Marneus Calgar's mana sink into a self-sustaining engine by relying on the passive discount of Puresteel Paladin, which reduces the equip cost of Lotus Ring to zero thanks to your artifacts. Once the two Astartes Warrior tokens enter, Marneus Calgar rewards you with a card draw for their entry, while Maelstrom Wanderer grants your newly minted army immediate haste. You then equip Lotus Ring for free and immediately sacrifice the creature to tap into its mana-producing ability, funding the next activation of Marneus Calgar to repeat the cycle indefinitely.
