Akron Legionnaire

An 8/4 body that shuts off your own attack step for everyone who isn't a copy of itself or an artifact creature: a finisher with a deckbuilding tax welded directly to its rate. At eight mana you are buying a body that hits like a freight train, and the only ways to widen your offense are to lean on artifact creatures (a colorless axis Legends was actively exploring) or to draw multiples. That is deliberate restriction, not an oversight: the design wants the Legionnaire to be the engine of attack rather than one swinger among many, and it punishes white's default plan of going wide and swinging with a full board. The mechanical shape (a giant whose presence locks down your other troops) is flavor-first, the kind of top-end creature that came with a sharp deckbuilding price attached to its stat line rather than a clean keyword stack. Modern white finishers solve the same "expensive body that ends games" problem with evasion, protection clauses, and ward; this one solves it by handing you a hammer and confiscating your other weapons.
