I understand they are meant to be ultra rare exclusives hence EX, but I'd still love for the filter to be there both in shop and collection even if just to know what they are since they are unavailable.

Having a filter in the collection might be an idea (but, as I will only ever have the one, it's not something that really affects me).

Putting them in the store is a different matter however as there is no possible way of purchasing them, unlike the SECs which can be purchased with a Joker card.

Totem have said that the cards will never be for sale so putting them in the store will probably just irritate people who can't buy them.
