Talk:Mudragon of the Swamp

Is "of the Swamp" a Series?
A series is a group of three or more cards that share an appearance in artwork, name, or effect similarity, but are not genuine archetypes due to lacking any support cards. We already have three cards with of the Swamp (沼地の, Numachi no) in their Japanese names, that share an artwork, and all have a Fusion-related theme. Any thoughts?
