Lotus Ring + Puresteel Paladin + Marneus Calgar + Samut, Voice of Dissent

Lotus Ring

Puresteel Paladin

Marneus Calgar

Samut, Voice of Dissent

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 clever engine turns Marneus Calgar's activated ability into a self-sustaining loop by leveraging a clever mix of artifact cost reduction and sacrifice mana. When Marneus Calgar creates two Astartes Warrior tokens, his Master Tactician ability triggers to net you a card draw, while Samut, Voice of Dissent stands ready to grant haste to ensure the board is primed for action. Thanks to Puresteel Paladin's metalcraft ability reducing equip costs to zero, you can instantly attach Lotus Ring to one of the newly minted tokens. Finally, sacrificing that equipped warrior to Lotus Ring yields the exact amount of mana needed to fuel the next activation of Marneus Calgar, letting you cycle through your deck and churn out tokens indefinitely.
