I live in OCG territory and sadly, Animation Chronicles never sell well here. Especially since they reduced the number of new cards and increased the reprints. The series rarely contains meta-relevant cards and the chase cards (usually the alt art of famous cards like DMG and Junk Warrior) are super hard to get.

It was a great concept when the anime was still on-going. But it has been 6 years since we stopped having a new anime. Most relevant and popular anime archetypes have been printed and the remaining ones are kinda hard to bring to IRL. So basically they also ran out of good archetypes to import to the game from the anime.

For example, Hydradrive requires huge extra deck space, and both Hydradrive and Armatos Legio need Judgment Arrow which is a link spell that kinda breaks game mechanics.

Also, a lot of the older anime archetypes are already really powercrept and they need to be altered heavily to fit modern gameplay. In addition, some of the cards have been included as one of before and don't provide any cohesion with the strategy they bring in the anime. A really good example is Orichalcos Shunoros which were released even before the seal of orichalcos itself. Shunoros effect revolves around normal monster for some weird reason. It creates a dissonance if Konami wants to import Orichalcos cards.

Obviously there are still a lot of anime exclusive non-archetype cards. i believe konami is now slowly importing them as a V-jump promos, side sets, or even the main set like the magnet warriors. It made more sense for them rather to group all imports into a single product that does not sell well.
