Hello, guys!
Pokémon releases the A cards, or cards that have an Alternate artwork. These are the newest ways on reprinting cards from the older sets. So that means, if for example, a new Shaymin-EX (Hopefully!) gets reprinted, this is no longer a Black Star Promo, but instead, a "Sub-card" of the card from the actual set. So, Shaymin-EX's card no. will be "77a/111".
This new kind of gimmick kinda bit sucks to me, as a TCG Player. Because, I can't no longer played those cards for the future formats, and I have to adapt on a new one. (Well, things always changed, and so we are.)
This thing kind of thinking of a something. Is this the sign for the extension of the Standard Format.
You see..
In 2008, Diamond & Pearl-on format was lasted for 2 years until HS-Unleashed, probably. The probable cause of that is, most cool, competitive, and playable cards in DP to Platinum didn't get some reprint, like Legends Awakened Uxie, Great Encounters Claydol, Platinum Crobat G, and so on.. (Except from the common cards like Switch, Energy Search, you know what I mean.) If this kind of gimmick stay on, until SM-era. We will have a possibly for an Expanded Standard Format in August or in 2018, but it's too far to happen. Well see about that!
