- Is it required to have a Basic Pokémon in your deck? For example, could I make a deck with just the fossils and no other Basic Pokémon in it?
- Starting with EX:Delta Species, there is now a requirement to have at least 1 Basic Pokémon in a deck in order to be considered a legal deck.

- Can you mix Team Magma and Team Aqua cards in the same deck?
- Yes. There is no rule preventing you from playing rival teams in the same deck. The cards generally work better within the same team, but it's up to the player how they build their decks.
