Okay, so, I wanted to mess around with “Magic: The Gathering Errata” today, and let me tell you, it was a bit of a ride. Started off pretty simple, you know?

First, I dug into what Errata actually is. Turns out, it’s basically like when the folks who make the game, Wizards of the Coast, decide to change the text on a card after it’s been printed. Like, they tweak the rules or how the card works. They update the Oracle text, which is like the official, current wording of the card.
Then I started poking around the Comprehensive Rules. These things are like the bible of “Magic”, and they get updated every so often. I found out that the last big update was on June 14, 2024, with the release of Modern Horizons 3.
I dove deeper into the changes. I noticed that the colorless mana symbol {C} is used both for representing one colorless mana and a cost that you can only pay with one colorless mana. And get this, {0} means zero mana, like a placeholder for a cost that doesn’t need any resources. Weird, right?
I also looked into the graveyard rules. Each player has their own graveyard pile, and you can look at the cards in any graveyard whenever you want, but you usually can’t change the order of the cards in your own graveyard. But apparently, in some tournaments, you can mess with the order.
- Then there’s this thing called “Flanking”.
- It’s a keyword ability.
- Basically, if a creature has it, and another creature blocks it, the blocker gets -1/-1. Pretty neat!
So after all that, I decided to actually try implementing some of these Errata changes in a casual game with my buddy. I printed out the updated card text and stuck it on the cards. It was a bit janky, but it worked! We played a few games, trying out the new rules, especially the colorless mana stuff and Flanking.

It was definitely interesting to see how these small changes could affect the game. It felt like we were playing a slightly different version of “Magic”.
Honestly, it was a fun little experiment. I learned a lot about the behind-the-scenes stuff that goes into making and updating a game like “Magic: The Gathering.” I might actually do this again the next time they roll out some Errata updates. Makes you appreciate the game even more, you know?
