My first recommendation for buying triomes is to check your area for a local game store
PSA graders closely inspect: Centering (front and back) Edge wear Corner sharpness Print lines, whitening, and surface flaws Even pack-fresh Pokmon cards can grade lower than expected, so careful inspection before submission is key
Each pack guaranteed a holofoil Pokmon and a holofoil energy card of its respective type
Before buying a card secondhand, research its value to make sure you're getting a fair price

Its quick to set up, easy to learn the basics, and then continues to challenge you as you develop your skills
