Fixer, Techno Terror

Black has drawn cards off life since Alpha, from Necropotence down to the humble Sign in Blood, but those engines simply charge you in mana or in raw life and let you spend the payment however you like. This one adds a second toll: nothing draws unless an artifact has hit the battlefield under your control that turn. That gate is what lets a repeatable card-draw tap sit on a fragile 2/1 body without breaking. Treasure, Clues, Food, and cheap Equipment stop being incidental byproducts and start being the trigger key that unlocks a card each turn; a turn that produces no artifact produces no draw, which is the tax that punishes durdling. Two life per card is the other cost, and it escalates in the opposite direction from the artifact clause: the artifact requirement can be satisfied for free most turns, but the life keeps ticking regardless, so a slow grind eventually eats into your own clock. The engine therefore points at decks already flooding the board with artifacts as a matter of course, and it rewards those decks specifically for turning the extra cards into pressure before the arithmetic catches up with them. Built around from scratch it is fragile; slotted into a deck that was going to make an artifact anyway, it converts overflow into a steady stream of cards.
