The kobold has been a part of Dungeons & Dragons since 1974. Like the orc and the goblin, it is the monster that most low-level adventurers will encounter. So it makes sense that they would release it as a Monster Card. It is one of those monsters that has been evolved over time visually. Originally being lumped into the goblin family before evolving into something more reptilian. In 3rd Edition, the kobold took a giant leap forward. No longer would their lineage be tied to common goblins, no these kobolds were now distant relatives of dragons.
