I once heard a story about a Land Destruction deck that dominated tournaments at some point in early Magic's history. The story as I remember it is that the deck ran heavy land destruction to deny resources to the opponent, and it won with another card, which I believe dealt damage based on lands destroyed.
The card in question was inevitably banned, and Mark Rosewater occasionally comments that it's not the card's fault the deck was winning, and Land Destruction in general should have been seen as the problem instead.
What is the name of the card that was banned this way?
