Casual

Casual refers to playing Magic: The Gathering without an attempt being made to have tournament-worthy decks or be really competitive. Casual players, making up a significant majority of the customer base for the game, are generally more concerned about having fun than winning. Casual games are often played with theme decks that possess a unifying idea, image, or motif, repeated or developed throughout. Listed here are a number of casual formats that range from somewhat goofy to completely crazy. With a few exceptions, there are no "official rules" for these formats.

As with sanctioned formats, most casual variants can be categorised into Constructed, Limited and Multiplayer formats. Some formatis only appear in Magic Online.

Challenge Decks

Like Horde Magic, Challenge decks are a cooperative multiplayer variant in which the players work together against a preconstructed Challenge Deck which pilots itself based on special rules and a simple turn structure. The players each have 20 life and take their turn simultaneously. Players may begin the game with up to two Hero cards in their Command zone to assist in defeating the Challenge Deck. The players win when they meet the Challenge Deck's win condition. The Challenge Deck is victorious if all of the players have been eliminated from the game.

Alternative

Fat Stack

If you're looking for a format you can play with friends who don't have Magic cards of their own, Fat Stack is ideal. To prepare, create two stacks of cards that are used as communal libraries. The first stack features cards that can't produce mana, and the second stack features only lands and other cards that can produce mana (such as Dark Ritual, Birds of Paradise, or Fellwar Stone).

Whenever each player draws a card, he or she may do so from either stack. (All players know which stack is which.) This includes the seven cards in each player's opening hand. Choosing which stack of cards you'll draw from each turn is a fascinating challenge: Do you want to draw ways to produce mana that will help you play the cards in your hand, or do you want to draw cards that allow you to use the mana you can already produce? Players share both stacks of cards as a library and also use a communal graveyard. You can play Fat Stack as a two-player game, or as a multiplayer Free-for-All.

Many players enjoy Fat Stack because the game setup is very quick once someone has put together the stacks of cards to be used in a game, and it allows players to participate despite not having a large collection of Magic cards.

Mental Magic

Sitting around waiting for the next round of your Magic tournament to start? A game of Mental Magic is just what you need to get you through the time. All you need is an opponent and a stack of nonland cards to form both of your decks. Players start with seven-card hands, just like in a regular game of Magic, but all players draw from the same library of cards.

Cards may be played in one of two ways:

1. Any card may be played face down as a basic land that's capable of producing any color of mana. Although these lands are basic, they have no subtypes (they're not Swamps, for example). Note that players may still play only one land on each of their turns.

2. A card may be played as any card in Magic with the same mana cost as that card—except for the card it actually is! For example, Fugitive Wizard (which has a mana cost of ) could be played as Cursecatcher, Unsummon, or Ancestral Recall, but couldn't be played as Fugitive Wizard. In order to "mentally" play a card, a player must be able to accurately describe its card text with no outside help.

Once a card has been named, that card can't be named again for the rest of the game. In fact, if a card is returned to your hand and you want to play it again, you can't name the card you named before. You have to choose a different card with that mana cost.

There are some additional Mental Magic rules that you can play with or not as your group sees fit. Cards in your hand, graveyard, or anywhere else other than in play have no names—but they do have types and subtypes. If you play Raise Dead or Duress, for example, read what's actually printed on the card. Also, library-searching effects don't work. If you play a spell or ability that tells you to search your library, that part of the effect doesn't do anything. For a more in-depth discussion, see Mike Flores's Mental Magic feature article.

Mental Magic challenges players' knowledge of Magic and allows for a quick, fun way to pass the time between matches. It also challenges players to figure out whether the card in their hand is better played as Ray of Command, Phantasmal Forces, or simply as a rainbow land!

Reverse Mental Magic

The rules in Reverse Mental Magic are the same as Mental Magic with a single twist: your opponent gets to name the card you're playing! Players still draw from the same communal deck of nonland cards, they can still play cards in their hand face down as lands that produce any color of mana, and cards still can't be played as themselves.

The difference is that you don't know what spell you're playing when you play it. For example, if you've got a card in your hand, you'll tap three lands, show the card to your opponent, and then your opponent tries to think of the least scary card with that mana cost and name it. Players can't help but enjoy themselves as they watch their opponents struggle to name weak cards, only to eventually run out of options and provide their enemy with something to do them in. Reverse Mental Magic is a great alternative for those players already well versed in regular Mental Magic play.

DC10/Type 4

DC10, sometimes referred to as Type 4, is a Magic: The Gathering multiplayer variant that leads to some wild situations. To play, shuffle up a stack of cards and place it in the center of the table. Any number of players each draw a hand of seven cards, then roll dice to determine who will play first. Play then moves clockwise around the table from the first player. That may seem like a pretty typical game of Magic, but things from there get a bit crazy.

First, there are no lands in DC10. Instead, all players have access to an unlimited amount of mana in any color or combination of colors they choose. But that doesn't mean everyone can simply play each card in their hand—the game restricts players to playing only one spell per turn. DC10 games are defined by big plays being trumped by even bigger plays, generally around a table of Magic enthusiasts loudly cajoling one another and enjoying a format that can truly be described as whimsical.

For additional variations to the game, some players choose to pre-design the stack of cards they'll play with (similar to building a cube for Cube Draft) or restrict participants to being able to perform actions only a certain number of times each turn (meaning a player casting the card Fireball might be able to spend only 10 mana, or a player activating a Masticore's ability could do so only 10 times).
