Local variations of Oldschool

Old School Magic (often referred to as 93/94, Magic 94, or simply Oldschool), mostly follow the modern Magic rules. But there is a section of page 35 in the Alpha rule book it abides by more than other formats.

"Be prepared to encounter house versions of this game when you play someone you haven't played before. These rules are a framework from which to start; after you know how to play, your play group may develop local rules, new ways to play particular cards, or other variations. Just be sure before you start that everyone is playing the same game."


As the format has grown a lot during the last three or four years, many communities have taken slightly different approaches to old school Magic. This is a part of the format and by no means discouraged. Most commonly a few extra reprint sets are legal, but some groups use some local B&R lists, erratas or game rules as well. Below are five of the most popular variations.


----------------

"Ravenna rules"

Used in many major tournaments in southern Europe, perhaps most notably the Ovino series tournaments, major conventions that recently have hosted old school tournaments with over 50 players. Also used by most local groups in Italy and neighboring countries.
 

In a nutshell: Same B&R as here, but a few additional reprint sets from 94/95. Italian printings of Legends and The Dark are legal. Revised is legal in English and foreign black border versions. Rinascimento/Renaissance is legal (but not Chronicles).

"EC rules"

Very popular in the USA, in particular in Chicago and surrounding areas. Most notably used during the US Eternal Weekend, where a major old school tournament outside the convention site hosted over 80 players last year.
 

In a nutshell: Strip Mine, Black Vise and Mishra's Workshop are legal to play as 4-ofs. The "Mana Burn rule" is in effect. Fallen Empires is a legal set. The Harper Prism promos from 1994 are legal (Arena and Sewers of Estark, note that Giant Badgder, Windseeker Centaur and Mana Crypt are not legal). Additional reprint sets allowed include all cards that a) Have the same art as the original printing, b) Have the same frame as the original printing, and c) Are not foiled (E.g. Psionic Blast from Timeshifted and Wrath of God from 6th Edition are legal, but not a foiled Psionic Blast from Timeshifted or Wrath of God from 7th Edition). The printings from Collector's Edition and International Edition (CE/IE) are legal to be played in decks. All languages are legal.

"ChannelFireball rules"

Supported by ChannelFireball.com, most notably used at side events at GPs organized by ChannelFireball around the world.

In a nutshell: Black Vise, Shahrazade and Mishra's Workshop are legal to play as 4-ofs. The "Mana Burn rule" is in effect. Fallen Empires is a legal set. The Harper Prism promos from 1994 are legal (Arena and Sewers of Estark, note that Giant Badgder, Windseeker Centaur and Mana Crypt are not legal). Additional reprint sets allowed include all cards that a) Have the same art as the original printing, b) Have the same frame as the original printing, and c) Are not foiled. All languages are legal.

"EudoGames rules"

Popular in the US West Coast, and was the first alternative rule set in the US. Used e.g. at Eudemonia outside San Francisco.
 

In a nutshell: Black Vise is unrestricted, but Mana Vault is restricted. Fallen Empires is a legal set. Additional reprints from Chronicles and Revised are legal. All languages are legal. Printings from Collector's Edition and International Edition (CE/IE) are legal to be played in decks, as long as the player using them uses double sleeves.

"BoM rules"

Used at side events at the Bazaar of Moxen tournaments, mainly in Europe.

In a nutshell: Black Vise is legal as 4-of. Fallen Empires is a legal set. Falling Star have special errata. The legal reprint sets are kind of complex, but basically everything non-foiled with old border except Timeshifted cards are allowed. The mulligan rule is Paris mulligan (the mulligan used between 1997-2015). There are a few local game rules that should be noted, e.g. Continous Artifacts that don't have any triggered effects are "shut off" when tapped (but those with triggers, as well as Mono Artifacts and Poly Artifacts, still work while tapped), the "Mana Burn rule" applies, and the stated-based effect that makes a player lose for having 0 or less life isn't checked except at the end of phases. A large number of misprinted cards are banned, like Alpha Elvish Archers and Oricish Artillery (though e.g. Alpha Cyclopean Tomb is legal). All languages are legal.

There are more local variants, but these are the most popular ones you are most likely to encounter today. As long as you note that Mana Vault is restricted in Eudo Rules you shouldn't have to worry about being able to play any deck following the "baseline rules" at any tournaments however. And if you use another rule variant and travel to Russia or Norway or some other place where they mostly use the rules stated here, the great majority of players won't mind playing casual games against a deck that contains Revised or a few Fallen Empire cards. Old school players are a friendly bunch, and usually not picky when they get the chance to swing cards against a new opponent.


Other notes:
  • The lastest B&R changes are discussed in Banned and Restricted update 2016. The B&R list is reviewed after n00bcon each year, and updated in May.
  • Some notes on the legal sets can be read in the posts The arguments on Fallen Empires and 93/94 by any other name.
  • Some notes on the B&R can be read in the post Banned and restricted: 1994 and now.
  • Some notes on earlier "timing" rules compared with today's rules can be read in the post All in good timing.
  • 1st of February 2012 Chaos Orb was unbanned and restricted. We use the errata in order to avoid people spreading out their cards to much. Note that you are allowed a fair flip, you may move the card you're choosing to target to the center of the playing area to get a good flip. If you use Xenic Poltergeist and Dance of Many to create a Chaos Orb token, please note that tokens should not be disrupting the gamestate. Do not use a bowl of soup as a token and flip over your opponents cards. Be reasonable.
