Magic the Gathering designer Richard Garfield rates Dungeons & Dragons as the most innovative game of all time. Nonetheless, in any ranking of influential games, Magic’s revolutionary design surely vies for a top spot. You might suppose that a card game like Magic would differ too much from a roleplaying game to have any influence on D&D’s rules, but Magic’s design shaped the D&D editions to follow. Today, innovations from Magic extend to the roots of fifth-edition D&D.

5. Templated text changed how rules get written—and the 3rd-edition design team.

When Magic’s designers faced the problem of bringing order to countless cards, they used templated text: they described similar game rules with consistent wording imposed by fill-in-the-blank templates. Today, the patterns of templated text appear throughout modern D&D’s rules.
But the move to templated text also lifted a D&D-outsider to lead the game’s third-edition team. Ben Riggs tells this story in a convention seminar.

Early in the development of third-edition D&D, Wizards of the Coast purchased TSR. Skaff Elias had served as a designer on several early Magic sets and ranked as Senior Vice President of Research and Development. Skaff felt that the upcoming D&D edition could fix “sloppiness in the rules” by using templated text. Skaff and Wizard’s CEO Peter Adkison told the D&D design team to switch the spell descriptions to templated text, but the team kept resisting his directives.

Eventually, the D&D team readied the release of a playtest document that still lacked templated text. They claimed rewriting all the spell descriptions according to formula would prove impossible because hundreds of spells would need templating in 48 hours to meet their delivery deadline. Nonetheless, Adkison and Skaff took the challenge themselves, working through the night to rewrite the spells and meet the deadline. Even after that heroic effort, the rules document that reached playtesters lacked the templated descriptions from the CEO and the Design VP. The design team had simply ignored their bosses’ hard work.

The failure infuriated Adkison. He lifted Jonathan Tweet to the head of the third-edition team. Designer Monte Cook remembers Adkison’s new directive: “If Jonathan says something it’s as though I said it.” Unlike the TSR veterans on the rest of the team, Tweet had started his career by designing the indie roleplaying game Ars Magica and the experimental Over the Edge. As a member of the D&D team, he convinced the team to adopt some of the more daring changes in the new edition.

4. Keywords now get careful use throughout the rules.

Much like Magic, D&D uses keywords to describe many elements in the game. Often the keywords bring few rules of their own, but other things in the game interact with the keywords. So Magic has no rules specifically for “white” or “green,” but cards with “protection from white” work in a special way.

In D&D, conditions like “charmed,” creature types like “beast,” and descriptors like “melee” work as keywords. Such keywords power templated descriptions like, “While charmed by this spell, the creature is…” and, “The next time you hit a creature with a melee weapon attack…” In early editions of D&D some words got treatment that resembled keywords. But before Magic proved the technique’s power, keywords in D&D hardly saw the pervasive, rigorous treatment they do now.

3. Specific beats general came from Magic, but started in a hugely-influential board game nearly as old as D&D.

In Magic, the text on any card can change the rules of the game, so a card like Platinum Angel can say, “You can’t lose the game and your opponents can’t win the game.” Among traditional games where all the rules fit on the underside of a box lid or in a slim pamphlet, this made Magic revolutionary. The original Magic rules explain, “If a card contradicts the rules, the card takes precedence.” In other words, specific beats general. Similarly, page 3 of the Player’s Handbook explains how when a game element breaks the general rules in some way, it creates an exception to how the rest of the game works.

Earlier editions of D&D included game elements that broke general rules, but the unwritten principle left new players to struggle with the apparent inconsistencies. Judging by how frequently D&D lead Jeremy Crawford restates the principle, players still struggle with it.

The principle of specific beats general dates to the revolutionary 1977 game that inspired Magic the Gathering and countless others. Bored with the familiar patterns of their Risk games, the designers of Cosmic Encounter wanted a game where every play felt different from the last. In Cosmic Encounter, each player controls a different alien species able to break the general rules of the game in some specific way. With more than 150 rule-breaking alien species in the game and its expansions, Cosmic Encounter offers endless, disruptive combinations.

2. With more reliance on rulings, D&D does less to separate flavor from rules.

Magic the Gathering cards typically fill any space left after their rules text with italicized flavor text. So, Platinum Angel might say, “She is the apex of the artificer’s craft, the spirit of the divine called out of base metal.” Other Platinum Angels share the same rules, but different flavor text.

Traditionally, D&D mingled rules and flavor text, but fourth edition fully adopted such separation. The power descriptions even duplicate the practice of putting flavor in italics. This practice fit fourth edition, which defined combat powers as tightly as cards. The designers aspired to create a game where flavor never bent the rules, so a DM never needed to decide if, for example, you can take ongoing damage from cold and fire at the same time.

In fifth edition, the separation mainly appears in the monster books, where rules appear in formal boxes while flavor comes between the rectangles.

1. Reactions came from Magic’s instants and interrupts by way of D&D miniatures.

In Magic the Gathering, players can act at any time, stopping another player with cards originally called interrupts. The constant activity helps make the game so compelling, but it forced the designers to develop rules to make sense of the actions and reactions.

In early editions of D&D, players might interrupt another turn for an improvised action, but such acts needed a DM’s ruling. By third edition these actions counted as free and still mainly relied on a DM. Counterspells used the system’s only means of interrupting—the readied action.

When Wizards planned a line of D&D miniatures in 2003, the company aimed to expand sales beyond roleplayers to gamers who favored competitive wargaming. The Miniatures Handbook turned third edition’s combat rules into “a head-to-head skirmish system for fighting fast, tactical battles.” The book’s authors included D&D designers Jonathan Tweet and Rob Heinsoo along with Magic designers Skaff Elias and Mike Donais. The new miniatures would come boxed in randomized assortments complete with cards describing rules for each figure, so in ways, the package resembled Magic. The competitive skirmish game could no longer rely on a DM’s rulings to resolve interruptions, but the team wanted some of the richer play suggested by a game like Magic.

The design collaboration worked. Elias and Donais brought experience from a competitive game with strict rules for timing interrupts and reactions. “While designing Miniatures Handbook, we realized that free actions hid a potential smorgasbord of cool new mechanics,” wrote designer Bruce R. Cordell. “We subdivided the free actions into immediate actions (a free action you can take when it isn’t your turn), and swift actions (a free action you can take when it’s your turn).”

Swift and immediate actions entered the D&D roleplaying game through Cordell’s Expanded Psionics Handbook (2004). “The concept that swift and immediate actions could serve as one more resource available to a player opened up new vistas of possibility, expanding options in the game.”

In fifth edition, swift and immediate actions evolve into bonus actions and reactions.
