Meet Shener! He has 55 black blocks, and represents the 55th note on a 59-TET scale, corresponding to a frequency of 466.620 Hz (assuming the 50th note out of 59 is 440 Hz). Due to him being pretty late (high degree) in this scale, he is associated with the detached dwarf planet Sedna. He likes playing card games with friends, especially when the game involved energy usage. His design takes advantage of the fact that there are 11 types of energy in PTCG (including Fairy and Dragon, but excluding Rainbow), implied through the large wheel in the design.
