Mystifying Maze

A defensive land that fights combat by undoing it. The activated ability does not destroy or bounce the attacker; it exiles the creature and returns it tapped at the next end step, which is a tidy way to phrase a Fog that only ever stops one creature. The exile-and-return wording is what makes the effect more interesting than its blunt cost suggests: it removes the creature from combat without killing it, dodging death triggers and damage-on-death payoffs the opponent might want, while also blanking any auras, equipment, or counters that were riding on it (those fall off the moment it leaves the battlefield, and the body that comes back is a clean copy). Because the return happens at the next end step rather than immediately, the creature also misses any trigger tied to staying tapped or any vigilance benefit, and arrives tapped just in time to do nothing on the swing-back. The price, four mana plus the tap every turn, is steep enough to be repeatable insurance rather than a tempo engine, and it competes with itself for the activation each combat. What it rewards is a slow deck willing to spend a whole turn's mana neutralizing the scariest attacker on the board, over and over, without ever spending a card to do it.
