It's worth mentioning why they stopped doing power level errata: because it was too much of a headache to keep track of and required players to memorize how the cards had changed from the versions printed.Whipstitch wrote:I referenced a legit power level errata already. Implying that power level errata never actually happened is ignorant at best and disingenuous at worst. They were using power level errata until '06 or '07 or so. They printed articles about power level errata and then they further explained why they moved away from using power level errata. For most of Magic's history power level errata was a thing that happened. It's trivially easy to google, so you may as well get in line behind ice9 to drop the subject.
A game that ended up collapsing under the weight of its own errata was the original Star Wars CCG. After about 10 sets, the errata document was a pretty thick booklet, and it was a major obstacle to just buying cards and starting to play. Especially since sets didn't sunset in that game: the only playing environment was basically "Type 1".
