Doomed Artisan

At the beginning of your end step this 1/1 spits out another Sculpture, and because each token's power and toughness read the total count of Sculptures you control, the whole population resizes in lockstep: when the fifth token enters, all five are 5/5s at once; the sixth turns them all into 6/6s. This is a shared, continuously updating size, not a stack of tokens frozen at whatever number they arrived on, and that distinction is what makes the board genuinely dangerous the longer it survives. The catch reads like a drawback but is the design's whole argument, and it lives on the Artificer rather than on the tokens: while it is on the battlefield, your Sculptures can't attack or block. That static clause tethers a snowballing artifact-creature army to a single fragile body. Kill the maker, blink it, or let it die, and the entire wall is suddenly free to swing, every Sculpture at its current shared size. The restriction is the price paid for a free, ever-growing token engine; without it a card manufacturing larger and larger bodies at no cost would simply win unattended. Instead it hands you a rising count of colorless artifact creatures: sacrifice fodder, convoke bodies, payoff fuel for any effect that reads the board rather than combat math. The card's job is to be the supporting engine that feeds a second piece, or to build the standing army you eventually take off the leash yourself.
