Soldier of Fortune

A repeatable shuffle effect stapled to a body, which sounds like a do-nothing until you notice the verb is "target player," not "you." That single word turns a deck-fixing utility into an attack on someone else's setup: any opponent who has stacked the top of their library (a fateseal, a Sensei's Divining Top spin, a tutor that leaves the card on top, a Brainstorm whose buried cards depend on order) can have that arrangement scattered for one red mana and a tap. The design here is almost entirely about who gets to point the ability, and Wizards left it open on both ends. You can shuffle your own draws to dig past a clump, or you can punish a tutor by reshuffling the prize back into the rest of the library before it can be drawn. The friction is real: it is a 1/1 with a summoning-sickness gate, a tap cost, and a mana investment per activation, so it does nothing to the board and answers nothing on the stack. What it answers is information and ordering, the resources most decks treat as free. That makes it a piece of pure interaction with a resource axis most removal never touches, and it has stayed legal and unchanged since printing precisely because the rate is so deliberately small.
