Lost Origin introduces a number of Pokmon and Trainer cards that play around the Lost Zone - and many of them made this list
If this deck can tighten up a bit against the more random decks, I think that it could be a real contender
Why would you do this and not just play Curiosity
If your collection is old and large enough, its very likely theres many cards in this pile worth 1-5$ so you are definitely leaving some money on the table but if you arent knowledgeable enough to spot these cards at a glance, its probably not worth it to enter all this into a tracking software, especially if you have no interest in selling single cards online
People can complain about Obsidian Flames all they want, but it's Charizard ex SIR so cool
I only cover the top handful, but there are a few others that go into this tier like Najeela, the Blade-Blossom decks
