How it works
Activate Krark-Clan Ironworks by sacrificing Optimus Prime, Hero, adding CC.
When Optimus Prime, Hero dies, its second ability triggers, returning it from your graveyard to the battlefield as Optimus Prime, Autobot Leader.
Activate Krark-Clan Ironworks by sacrificing Optimus Prime, Autobot Leader, adding CC.
When Optimus Prime, Autobot Leader dies, Luminous Broodmoth triggers, returning Optimus Prime from your graveyard to the battlefield as Optimus Prime, Hero with a flying counter on it.
Repeat.
This clever loop harnesses the unique design of double-faced transforming commanders to continuously recycle Optimus Prime, Hero between its two distinct faces. By sacrificing Optimus Prime to Krark-Clan Ironworks for mana, each face triggers its respective rebirth mechanism—either the card's native death trigger on the front side or Luminous Broodmoth on the back—to resurrect it as the opposite face. Because Luminous Broodmoth grants a flying counter to the returning creature, the back side becomes a creature *with* flying, neatly bypassing the Broodmoth's restriction and allowing the front side's death trigger to take over on the next iteration.
