In 1995, Wizards of the Coast came out with a compilation expansion featuring cards from previously-released Magic: The Gathering expansions. It didn't go over well.
For one year, Deathtouch was such a broken ability that Wizards of the Coast had to drastically alter it so that it could work as intended.
More than a decade ago, Wizards of the Coast ended one of its longest-running Magic: The Gathering formats.
There was a creature in Magic: The Gathering that appeared on a handful of cards in only one expansion, then never was seen again.
This may come as a surprise to many, but Magic: The Gathering misprints are not exactly a thing of the past.
