Rationale

Undercity Informer was banned in both Pioneer and Legacy due to its central role in the "Oops! All Spells!" archetype. This strategy utilizes the card—in conjunction with Balustrade Spy—to mill a player's entire library, creating an extremely consistent, repetitive "one-card combo deck." The ban was necessitated by the deck's ability to generate high levels of turn-one consistency and power, which was deemed detrimental to metagame diversity and contributed to an overall unhealthy and predictable impact on the format.
