What land destruction enabler was wrongfully banned in the early history of Magic: the Gathering?
Dingus Egg was banned once upon a time, and it does 2 damage to the land's controller when a land is put into the graveyard from play. A few of these do a lot of damage per land, I've seen it in a few land destruction decks over the years. It's not currently banned in any formats it would otherwise be legal in.
