LEGO The Mountain Cave (21137) was released in 2017 as part of the Minecraft theme, with 2,863 pieces and 6 minifigures. That makes it the 1st largest of the 202 Minecraft sets in the catalog. It was one of 9 Minecraft sets released that year (see them all). Released in 2017, 9 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
