During setup, when I draw my 7 cards to see if I have a basic and I have a Mysterious Fossil in my hand, would I have to put it down, or could I choose not to?

Compendium said:Q. If you have basic and fossil Pokémon in your hand at startup, can you choose to play only the fossils and not the basic?
A. Yes. You can play "just" the Fossil Trainer cards, if you have fossils and a basic. If your opening hand has Fossil Trainers only, but no Basic Pokémon cards, you must choose a Fossil Trainer to place active. (Oct 16, 2003 PUI Rules Team; Jul 27, 2006 PUI Rules Team)
