Players collect different Pokemon monsters who each have different powers: often based on elemental powers--such as water, fire, wind ("Flying") and earth-based ("Ground") abilities--or on magical powers and the supernatural (such as the Psychic, Dragon, Ghost and Fairy types)
Charmander and Charmeleon, which are also reprints from the 151 set are now appearing in foil variants
I would expect it to follow a similar trajectory to Imperial Recruiter which went from being a $340+ card to around $120 with the reprints available for under $30
Theres also the possibility that the buyer gets just one card of notable value in the entire booster box
For noncreature Stax, you've got Chalice of the Void, Cursed Totem, Thorn of Amethyst, Deafening Silence, Grafdigger's Cage (which your Commander's ability gets around btw, very strong here), & Rule of Law as a few solid options
Counterfeiters moved on to other card games that were hot at the time
