[Searching for trade] Black star promos Yellow alternate not listed for the game

[Chasista]

I was asking myself how to check and find the Yellow alternate cards in the Filters when you're going to search a card in Trading section. You know, you enter Trades, Public offers, then choose Cards and in Card filters, how to find that Yellow alternates?

 

I've just realized myself you can search for the exact card entering the card number. I just thought letters were not allowed, but yes, you can search for Set + Card+a (like BKT 146a).

 

So I went to try to find Yveltal EX: XY Black star promo 150a.

 

Mmm no, the text in the box becomes red = doesn't exist.

Ok, let's try with another, Jirachi XY Black star promo 67a. Oh, text in red.

 

You can go ahead and Intro that red text, but it searches for the 150, or the 67. All of them. Mixed. The 150 and the 150a so you need to check trade by trade and in some it's the 150 and other trades it's the 150a. Filter doesn't filters.

 

Same with Jirachi, both appear in trades, 67 and 67a. Mixed.

 

This doesn't happens when you search for a set Yellow alternate promo. Darkrai GX BUS 88a? There it goes, only the exact Yellow alternate card in trades. Delinquent BKP 98b. There goes, perfect. Only the exact card when you search in the sets.

 

Try with S&M Black star promos, just in case it's an old thing of XY Black star: Tapu koko S&M Black star promo 30a. Mixed again, SM30 and SM30a

 

it seems Black star promo Yellow alternate cards are not added to the list of existing cards themselves so filter doesn't recognize the Alternate Yellow cards as unique or different than the regular Black star promo.

 

Am I right?

 

Thanks
