Tony Stark // The Invincible Iron Man

The genius on the front half is an artifact selection engine with a body flimsy enough (1/3, no evasion) to reflect a man in a workshop rather than a suit: a repeatable dig four deep for the specific gear you need, filtering the rest back into the deck. The transform clause is where the flavor and the mechanics lock together. Six mana at sorcery speed converts the tinkerer into the finished machine, and the machine plays a different game entirely: flying, haste, and a combat-step trigger that cheats an artifact out of hand for free each turn, auto-equipping any Equipment to itself. The two faces model an assembly loop directly. Tony finds the parts before the flip; Iron Man deploys them after, turning stockpiled artifacts into either instant board presence or a growing suit of gear on a hasty flier. What holds the payoff in check is the sequencing tax: the front side does the searching but cannot deploy, the back side does the deploying but cannot search, so the card wants you to load your hand while you are still Tony, then commit the transform once the arsenal is stocked. It is a two-card engine folded into a single legendary, with the six-mana sorcery-speed transform standing in for the vulnerability window a self-cheating combat engine would otherwise demand.
