Master's Guide-Mural // Master's Manufactory

A wall that pays for itself twice over. On entry it stamps out a 4/4 Golem, so even while you save up the transform cost you are never holding a blank artifact hoping to reach the good half. That good half is a factory: once transformed, it taps to mint another 4/4 Golem on any turn an artifact entered under your control, converting a one-time enters trigger into a recurring supply of bodies. The craft price is genuinely heavy, exiling this artifact plus another artifact from play or the graveyard, and the sorcery-speed restriction on the craft ability keeps you from folding it into an untapped-mana rush. What holds the design together is that the back face's activation asks the deck to already be doing something it wanted to do: churning permanents. A deck that plays no artifacts leaves the Manufactory idle; a deck built to blink, recur, or chain cheap artifacts turns it into a closer that outproduces removal, and because the ability only requires that an artifact entered this turn, the Golems arrive at instant speed to ambush attackers or rebuild a swept board on the opponent's end step. The fuel clause reaching into the graveyard as well as the battlefield is the detail that makes the transform reachable in a grindy, resource-dense build without handing it to a deck that just wants a cheap beater. Both faces do real work: a defensive body on the front, a token engine on the back, and no dead turns in between.
