Geological Appraiser
Timeline
Rationale
Geological Appraiser was banned in Pioneer and subsequently in Explorer due to its capability to enable overly aggressive and potent early-game strategies. The card was integral to new strategies introduced by the "discover mechanic," which allowed players to generate powerful, board-dominating effects through cloning. This ability allowed decks to generate lethal or game-ending results too early in the format, exerting excessive pressure that was deemed detrimental to the long-term health and strategic diversity of Pioneer.
