Lotus Ring + Puresteel Paladin + Marneus Calgar + Anger

Lotus Ring

Puresteel Paladin

Marneus Calgar

Anger

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 loop transforms Marneus Calgar's activated ability into a self-sustaining engine by flooding the board with Astartes Warrior tokens while simultaneously fueling your hand. Puresteel Paladin makes this mana-positive and mathematically possible by reducing Lotus Ring's equip cost to zero once you have enough artifacts, letting you effortlessly shuffle the Ring onto each new token to sacrifice it for mana. Meanwhile, Anger rests quietly in your graveyard to ensure any hasty red-producing setup or synergies can operate immediately, though the primary loop relies entirely on Marneus Calgar churning out tokens to repeatedly trigger his own card-draw ability alongside the Paladin's equipment-entry draws.
