This clever loop turns Diamond Lion into a self-sustaining mana source by pairing its sacrifice ability with Koll, the Forgemaster's recursion trigger. Because Ronin Warclub automatically attaches itself to the Lion upon entry, the Lion is always equipped, allowing Koll to bounce it straight back to your hand the moment it dies. Anger plays a vital supporting role from the graveyard, granting your creatures haste as long as you control a Mountain so you can replay the Lion immediately without waiting. Through this seamless cycle, you generate infinite colored mana, death triggers, and storm count to overwhelm your opponents in formats like Commander and Legacy.
