Svogthos, the Restless Tomb – Ravnica: City of Guilds uncommon. Svogthos was once an Orzhov cathedral, but the Golgari took it over for their guild hall and brought it to life. According to rumor, whenever the center of Golgari territory shifts, Svogthos itself moves to follow.
Lotleth Troll – Return to Ravnica rare. The Lotleth are the Golgari's irregular faction of undead, necromancers, fungus-binders, and other members associated with the restless dead. Although most Golgari undead are mindless fungal constructions maintained by necromantic magic, the Lotleth do have some more or less intelligent undead among them, plus a few higher-ranked necromancers who speak for the faction.
Jarad, Golgari Lich Lord – Return to Ravnica mythic rare. Jarad Vod Savo was an elvish archer, brother to the Golgari’s previous leader: Savra. Jarad ended up sacrificing himself to protect his son from Rakdos, then through necromancy brought himself back to life to reign over Golgari after his sister’s demise. As an undead lich necromancer, he has the power to hold onto the position of Golgari guldmaster.
Rare-B-Gone – Unhinged rare. When we planned Unhinged previews back in 2004, we thought we were pretty clever with Rare-B-Gone. What could be a better place to preview a rare-destroying card than Building on a Budget? Even eight years later, that still seems like the right idea!
Common Bond – Return to Ravnica common. Common Bond shows a wolf and its elf rider. Their magical connection is shown by the glowing green eyes they both have.
Izzet Signet – Guildpact common. Most of the guild symbols were changed a little between the original Ravnica block and the current one. Jeremy Jarvis went over each of the changes in this article, but one of the symbols has a canonical in-game reason for being updated! According to Izzet Signet, Niv-Mizzet frequently changes the guild's logo to make himself look better.
Niv-Mizzet, the Firemind – Guildpact rare. The first appearance of Niv-Mizzet, the smartest living thing on the plane of Ravnica, was in Guildpact and featured this unusual flavor text:
Niv-Mizzet, Dracogenius – Return to Ravnica mythic rare. Although Niv-Mizzet is the leader (and namesake) of the Izzet, he rarely concerns himself with day-to-day operations. Instead, Niv-Mizzet concentrates on elaborate long-range plans while his personal court (the Izmundi) keep him informed on the outside world.
Archon of the Triumvirate – Return to Ravnica rare. Archon was the title of the chief magistrate in ancient Athens; in Magic it has come to represent a humanoid being riding atop a winged animal. Archon of the Triumvirate is the first of Magic's Archons to be multicolored.
Ebon Praetor – Fallen Empires rare. The idea of power-and-toughness-altering counters on creatures was introduced in Fallen Empires. They've been reduced to just +1/+1 and -1/-1 counters, but originally there were all sorts of configurations, like Ebon Praetor's -2/-2 and +1/+0 counters. Duelist #4 had a convenient punch-out sheet of the Fallen Empires counters, and you can see it here.
Jedit Ojanen – Legends common. For a common vanilla legend, Jedit Ojanen has left quite a legacy. The second book of the second Legends trilogy was about Jedit Ojanen. There were two comic books called "Legend of Jedit Ojanen" in 1996. An alternate Jedit even returned in Planar Chaos as Jedit Ojanen of Efrava.
