Imp (遊精 ; yuusei) is a family premiered in BS01. Imps are primarily Green, but during the early stage of the game, Yellow also shared the family. They are comparable to Fairies, but animal-themed. Green primates or humanoid animals are also in this family. Opposite to the Blade Beast family, the Imps are mostly herbivorous animals which look defenceless.
During the time The SephirothicSheepDeity Sephiro-Aries was released, the family leant slightly towards a control play style. During the God-King era, new Imps with the motif of rabbits, which also had the Winged Beast family, were released. Eventually, in Ultra Advent era, The Grandwalker Saraswati was released, leading to a deck that actually focuses on Imps.
