Can’t wrap my head around why Haxorus is so underrepresented in the TCG.

Doesn't make sense at all. Haxorus is not only one of the coolest designed Pokémon, its shiny coloration is one of the best looking as well. Fraxure has a full art print in Shrouded Fable by Haxorus got nothing. Why? To make matters worse, Paradise Dragona would've been the perfect opportunity for a new Haxorus print but that didn't happen.
