Summoner (召(しょう)喚(かん)士(し) Shōkanshi) is a series of monsters that debuted in Starter Deck 2014. They are based on the Four Symbols of the Chinese constellations.
Their artworks imply a relation to the Empower series as they each seem to transform into one of the four creatures that make up the Chinese Constellations. The fifth creature, The Yellow Dragon, represents the center of the constellations.
