Spell-copying in red usually means a fork effect on the stack, a rider that duplicates whatever you were already casting for a chunk of extra mana. This inverts the transaction: instead of paying to fork, you feed an artifact to the graveyard, and the copy comes with the standard freedom to redirect. That reframes the whole ask. The engine wants a deck stocked with cheap, expendable artifacts (Treasure, Clue tokens, mana rocks that have already done their job) so that every burn spell, every removal instant, every counter can arrive twice while the board is being ground down elsewhere. The sacrifice is the throttle: no fodder, no copy, which pushes you to build a self-replenishing artifact stream rather than assume one will be lying around. The body is worth protecting because Ward paid in life rather than mana is the harder tax for a control opponent to route around; three life is cheaper than three mana in the abstract, but it compounds across a game, and a mirror or a burn-heavy opponent will not always want to hand it over. The 4/4 is large enough to close a game on its own once the artifact tank runs dry, so the design does not strand you when the loop stops. It is an artificer built to launder your spent artifacts into extra spells, and its ceiling scales with how well you can keep the graveyard fed.
