https://imgur.com/9ipyA4u - STN currently has 1 for sale @ 23 but I'm not sure for how long; so going to include up to 25 Keys given how recent that sale was and since there is a possible other 25 Keys sale

- Excluding 22 since it was a bot dump

Taking 23 - 25 Keys (lmk if I should take a different range idk)
