Ampharos Prime from HS Base, and quietly one of the most wanted Primes of the lot. Kent Kanetsuna's artwork with those glowing red orbs against the dark background still looks incredible.

I ended up with two copies over the years - Sleeved and binder-kept since I got it, front and back photos shot flat so you can check the corners and centring.

If you're building an HGSS Prime run, this is usually the one people struggle to find.
