Mishra, Artificer Prodigy

The historical Mishra was the brother who hoarded artifacts, and this version turns that flavor into a tutor-on-a-stick that fires every time you cast an artifact. The clever part is the search zone: graveyard, hand, and library, in any combination. Cast a single copy of an artifact and you can pull its twin straight onto the battlefield, no second casting cost paid, no second mana spent. Redundancy becomes the point of the deck: run multiples of the artifacts you most want doubled, and every cast becomes a two-for-one that also sidesteps the second spell going on the stack at all (the fetched copy enters directly, immune to counters aimed at the cast). That last detail is the design tension worth dwelling on. A 4/4 body across three colors is a steep ask for a creature whose payoff only triggers on artifacts, and the Grixis shard of blue, black, and red leans toward a build that already wants to cheat costs and abuse enter-the-battlefield triggers. The reward scales with how willing you are to warp a deck around it: stack copies of an artifact with a powerful entry effect and each cast resolves into two of them. It is a build-around in the truest sense, a payoff that does nothing in a stock list and a combo engine in one tuned to feed it artifacts worth duplicating.
