The Izzet League are charged with attending to Ravnican civic works,  including water supply systems, sewers, heating systems, boilers, and roadways.    In addition to carrying out these functions, the Izzet members — obsessive, keen, and creative intellectuals, who often have short attention spans   — are known to perform magical experiments, ever with reckless abandon and sometimes with spectacular but severe results.   Unlike the other guilds, the Izzet do not strive for hegemony of the city and plane of Ravnica or power at all; integral to the Izzet League, a guild of masters of both theoretical and applied science and spellcraft, however, the passionate seeking and thirst for knowledge.  Combined with their drive for discovery and child-like curiosity, the brilliant but capricious and whimsical Izzet magewrights jump to and from ideas as they see fit, discarding old ideas for new ones that attract their attention.  In this regard, they can likened to ambivalent or benevolent mad and absent-minded scientists/professors.  
The brilliant of Ravnica flock to Niv-Mizzet, and the most intelligent being on Ravnica. Powerful enough to live to tell the tale of his fight against the nephilim and capable of seizing control of the city and plane of Ravnica, Niv-Mizzet is content with not taking over Ravnica, in large part due to his fickleness and odium for monotony, as ruling and running Ravnica would become tedious.
Although varieties of dragon-kin, such as drakes, wyverns, and wurms, are present in Ravnica, Niv-Mizzet is said to be the last true dragon. As would be reasonably expected of him due to his vanity, Niv-Mizzet has numerous lesser clones of himself; other than as his underlings, the full purpose of these dragon clones, however, remains unknown. Testimonies to the significance as well as vanity of Niv-Mizzet are reflected in the uniforms of Izzet League members and the names of inventions or structures, such as Mizzium, a metal invented by Niv-Mizzet; Nivix, the guild hall of the Izzet League ; and Izzet, the name of the guild itself.  The alchemically-boosted clothing of the Izzet are flamboyant, with bright fabrics dyed in the colors of their draconic leader's scales and shiny metals.
Ral Zarek is a blue and red-aligned planeswalker, born to the city plane of Ravnica and a high ranking guildmage to the Izzet League. While he has ascended, he's managed to hide this fact from Niv-Mizzet, a very impressive task. Ral is the chief researcher investigating the ancient codes laid out in the Tenth District, the leylines and secrets that make up the Implicit Maze that so fascinates Niv-Mizzet. Ral then takes the role as the Izzet's maze runner after killing the rightful Izzet maze runner.
The Firemind is an extrasensory link with Niv-Mizzet's consciousness and omniscience, between selected, worthy Izzet League subordinates, Crixizix being one, and Niv-Mizzet himself. Members of the Izzet League whom are deemed worthy must first pass a test before they may communicate with Niv-Mizzet.
Supposedly created during the Katazar-Razblat Elemental Symposium, weirds are the semi-sentient, walking-paradox result of a fusion of elementals of opposing elements, of fire and water and of earth and electricity. Weirds are a creature type unique to the Izzet League, and function as ubiquitous lab assistants and "pets" of Izzet League members.
Founded by parun Niv-Mizzet, an ancient, brilliant, capricious, and narcissistic dragon, the Izzet League continuously create and destroy and are obsessively driven by a desire for new discoveries. Being the analogue of scientists and engineers on Ravnica and the masters of innovation and spellcraft, the Izzet are also responsible for the design and implementation of most of Ravnica's infrastructure and inventions.

Introduced in the Magic storyline in the novel Guildpact, the Izzet League are depicted as passionate thinkers and, largely, via the viewpoint of Crix (later Crixizix), a goblin courier who initially serves under a magelord Zomaj Hauc but is later chosen, and promoted, by Niv-Mizzet.
Return to Ravnica block
After fighting with the nephilim, Niv-Mizzet was not seen for a while. Former guildmages wonder what use this new-found freedom could mean for the Izzet, but without word from their guildmaster, the Izzet League becomes scattered and chaotic.[fact? citation needed]
Most Ravnicans saw the disappearance of Niv-Mizzet as the end of the Izzet guild. It isn't until the emergence of large Izzet works being built and strange warehouses humming with manacoils throughout the night do Ravnicans begin to change their presumptions. The ancient dragon parun doesn't have to be visible to control his guild. During his absence, he uses the power of the Firemind to reach out to his guildmages with a complex array of new and mysterious projects for the Izzet League to work on.[fact? citation needed]
In the game
Designed as "polycast" and with the Izzet League's in-game identity being one heavily oriented around instant and sorcery spells, replicate is a static and triggered ability that allows a card's controller to copy a spell with replicate as many times as the card's replicate cost was paid.
Return to Ravnica: Overload
Inspired by Ken Nagle's The Great Designer Search Radiate-inspired Dispersion mechanic, like Replicate, Overload is a static ability solely featured on instant and sorcery spells. Unlike Replicate, however, it enables its controller to play a spell with Overload for its Overload cost to change the range of a spell from a single target to each possible target. Issues in designing and developing cards with Overload included the rarity of the cards, the playability of both sides of the cards, and the guaranteeing of a one-sided effect, without inadvertent side-effects.
