Whenever another nonartifact creature dies, return it to the battlefield under your control face down and tapped. It's a 2/2 Cyberman artifact creature.
At the beginning of your end step, each opponent faces a villainous choice — Each artifact creature you control deals 1 damage to that opponent, or you draw a card and chaos ensues.
Missy turns every creature death across the table into a tapped 2/2 Cyberman artifact under your control, snowballing a wide army from board wipes, sacrifice, and removal. Each turn you grind value with the end-step villainous choice—either chunking opponents with your growing artifact army or drawing cards (with chaos). You win by overwhelming with stolen creatures, going wide for combat or aristocrat damage, or assembling artifact-based combos.
