Neurok Spy

Evasion that bills the opponent for their own deck. The conditional unblockability is keyed to whatever artifacts the defending player controls, so on a plane built around the metal it reads as a near-permanent fixture: when everybody's mana, equipment, and threats are artifacts, the condition is almost always satisfied. The clever part is that the controller's own board is irrelevant; the evasion is a function of the opposing battlefield, getting stronger the more the other deck commits to artifacts and switching off entirely against the rare board that holds none. That makes it a barometer as much as a beater: a 2/2 that connects reliably against the format's natural state and idles against decks that have abandoned it. The Rogue typing and the spy flavor land cleanly, and the keyword logic runs backward from the usual unblockable line, ceding control of its own evasion to the opponent and trusting the surrounding metagame's gravity to keep that switch flipped on. Its power level is written into the environment rather than the card itself, which is why a heavily artifact-themed world can afford to print contextual evasion at common-grade rates.
