Calibur because of purple Rider syndrome imo lol just like Horobi but both were pretty badass during their series. I see dragonic knight dropping in price once Primitive Dragon releases because it was the only upgrade form released for Saber for awhile that's played a part in it's price maintaining. Dragonic Knight is a badass design but so is Jaou Dragon and we seen how fast he dropped in price that is still a head scratcher.

As for Espada...maybe because of the accessories and the fact I know a lot of people favor his design out of all the Saber Riders and yeah tertiary Rider that many argued was the secondary Rider.

I'm still surprised at how long they waited to reveal and confirm Primitive Dragon when they already had the mold done technically when they revealed Arabiana Night Espada
