Biotransference

A type-alchemy engine, and the transformation it performs is the whole strategic pivot: creatures you control become artifacts, along with your creature spells and creature cards you own off the battlefield. That single blanket rewrite retunes an entire deck's affinity. Suddenly a board of creatures counts toward artifact-matters payoffs, feeds artifact tutors, and reads as fuel for cards that never intended to see a body. The second half turns the causation around: because your creature spells are now also artifact spells, casting them triggers the lose-life-and-create clause, so a creature-heavy list spits out Necron Warrior tokens simply by playing on curve. The life loss is the meter that keeps the token stream from being free, a small aristocrat-style tax that most black decks can absorb and some actively want. What makes the design sit oddly among enchantments is that the enchantment adds no stats of its own the moment it lands: it removes nothing and blocks nothing, only rewriting types until you cast the next artifact spell. Its power is entirely combinatorial, a lens that alters what every other card in the deck is and what casting them does. That places it among the type-granting enablers that only earn their slot once a shell has been assembled to exploit the new type, a static affinity-turner rather than a value creature. Dropped into a list with nothing to convert, the enchantment is inert, and that inertness is the point.
