LEGO Invention Designer (Kits 10 - 12) (20215) was released in 2013 as part of the Master Builder Academy theme, with 678 pieces and 3 minifigures. That makes it the 1st largest of the 14 Master Builder Academy sets in the catalog. Released in 2013, 13 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
