This intricate loop turns a simple activation into an engine of escalating rewards, powered by Clan Crafter granting your commander an artifact-sacrificing outlet to fuel the engine. When you sacrifice a Clue, Lonis, Genetics Expert not only triggers to push a +1/+1 counter onto another creature, but its counter-placement ability also feeds right back into creating even more Clues. The presence of Mondrak, Glory Dominus doubles every single Clue token created along the way, ensuring you generate a surplus of artifacts. Finally, Krark-Clan Ironworks steps in to convert those abundant Clue tokens into the colorless mana needed to keep the cycle turning infinitely.
