Weathered Bodyguards

The whole battlefield routes through one creature, and the catch is the word "untapped." This is a redirection wall built on a deliberately fragile clause: it eats every point of unblocked combat damage as long as it stands ready, so a board full of attackers becomes irrelevant the moment the bodyguard is standing guard. The seam is that the protection only holds while it is untapped. Send it in to attack, tap it with a Twiddle effect or an opposing tapper, and the redirection evaporates that instant, leaving you exposed to the same swing it had been absorbing. That on/off switch is what keeps a 2/5 from being a one-card lock against aggression. The 5 toughness matters more than the damage it stops: most single attackers cannot kill it through combat, so it survives to reset each turn, but a sufficiently large unblocked swing still trades it away in a single hit because all that damage stacks onto one body. The morph cost gives the line a second use, letting you deploy it face down as a 2/2 early and flip it up later, turning what reads as a passive defensive piece into a reactive answer to a planned alpha strike. A defensive engine with an exploitable hinge: it never warped any format because the readiest answer is to tap it down with tempo the attacker already wanted to spend.
