shining pokemon card First Edition Base Set Charizard Holographic Pokémon PROXY [Fighting]2 Shiny Pokémon take center stage

I played in the Junior Super Series when I was 13-15, he tells us

I sort by color, which is convenient since many players (in my anecdotal experience) look for cards for specific Commander decks, so they might want to skip entire colors

However, there are those who say (and here it may be a majority opinion) that the effort is not worth it, as the prize pool at the end of the season can be mediocre compared to the time dedicated to staying in the Mythic and, even so, being in the Mythic you may not be ranked high enough to be invited to an event

Not sure what to think of this tbh The stamps themselves look legit in your first picture, except maybe the sixth on in the first picture
