I have some questions regarding booster draft format for the Pokémon tcg: 1. Most sources call for six boosters for each participant, but this seems like quite a lot. Is it possible to draft with five or four? Has anyone had good/bad experiences in doing this? 2. What is generally a good energy to Pokémon/Trainer ratio when drafting? Is there a general average number that is used, or is this number hugely different from deck to deck? 3. Where would be a good place to purchase basic Darkness and basic Metal energy cards (approx. 100 of each) for use in draft? Answers to any of these questions would be greatly appreciated. Thank you.
