After Indigo Disk, these will become the only pokémon not available in any Switch game released till now. Out of these, only Furfrou is available in a Gen VII game (USUM), while all the others are only catchable in XY (a decade old game). So that means that, unless you’re using GO, and unless they release a new game in which you can obtain them, once Bank closes these pokémon are going to be virtually impossible to catch.

A prayer for anyone having one of these as their favorite pokémon
