DECK BUILDING TIPS:
A deck = 60 cards
Sort your pokemon by type (grass, fire, etc.)
Sort your energy cards by type
Pick just 1 or 2 types to use in your deck
Pick 25 Pokemon, 25 matching energy cards, and 10 trainers
NOTE: Some pokemon are "basic". You can always start with these.
Some pokemon are "stage 1" or "stage 2". You can't play these unless you have the cards that they evolve from (the card will tell you in tiny letters who it evolves from). Don't include stage 1 or stage 2 cards unless you also have the cards that they evolve from.
