Lotus Ring + Puresteel Paladin + Marneus Calgar + Dynaheir, Invoker Adept

Lotus Ring

Puresteel Paladin

Marneus Calgar

Dynaheir, Invoker Adept

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 turns Marneus Calgar into an engine that feeds itself by leveraging Puresteel Paladin's metalcraft ability to reduce Lotus Ring's equip cost to zero. When Marneus Calgar uses its ability to create two Astartes Warrior tokens, its own triggered ability rewards you with a card draw, and Puresteel Paladin helps you draw even more when equipment enters. You then equip Lotus Ring for free using that metalcraft discount before sacrificing the equipped token for mana, allowing you to easily fund the next activation. While Dynaheir, Invoker Adept shares the battlefield, her haste-granting and ability-copying prowess sit alongside this engine, rounding out a powerful setup available in commander, legacy, oathbreaker, and vintage.
