Togedemaru #104 Pokemon Phantasmal Flames Keep track of your collection value over time
Because its multiplayer and everyone kind of keeps each other in check, its not nearly as competitive as one-on-one formats. [2] Assemble 60 cards that you want to play to make a deck
If your deck is full of cards like Fauna Shaman and Chord of Calling so you have a lot of access to single copies of utility creatures in your deck, theres a lot of extra value to each extra bullet you can fit, and on top of that, the more narrow bullets you put in, the less you want the odds of accidentally drawing one of them to be, so the more cards you have, the less likely your are to draw a narrow bullet that youre hoping to only see when you search for it
If you want graded cards, start with the PSA 10 collection and exact-card verification checklist
Drawing cards is always helpful and gives you more options
Collectors who started with the English TCG often find the JPN rarity system easier to navigate once they realize SAR = Special Illustration Rare and UR = Hyper Rare
