Puresteel Paladin

Marneus Calgar

Cyclops of Eternal Fury

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.
