Recently started play ptcg and opened a couple booster boxes but now I have so many usless doubles Idk what to do with them any ideas
Its annoying because all the websites seem to only buy reverse holosDoubles are actually good. Running multiple copies of a card in your deck increased the chances of you drawing the card, overall making the deck more consistent. If you want to get rid of the doubles, though, there isn't too much you could do. You could sell the cards on TCGPlayer or similar sites, or at your local card shop. You could also try going to your league and seeing if anyone there will trade for the cards you don't want (though if you don't want them, other people might not want them either).
Also, welcome to Pokebeach!
