By weaving Bludgeon Brawl into the mix, every noncreature, non-Equipment artifact on your board—including Chrome Mox—is transformed into an Equipment with an equip cost equal to its mana value, which in Chrome Mox's case is a cool zero. Because you can target your own creatures with that zero-cost equip ability repeatedly, you can continuously target Cephalid Illusionist without spending any mana. Every single time Chrome Mox targets Cephalid Illusionist, it triggers the Illusionist's mill ability, resulting in an endless loop of self-milling to fuel your graveyard strategies.
