Lunatone LV 31 . GE 76/106 powr: Gravity Change Once during your turn (before your attack), you may discard a card from your hand. Then, if you have Solrock in play, draw a card. This power can't be used if Lunatone is affected by a Special Condition.So what happens if you don't have a Solrock in play? Can you still chose to discard a card? Second Question: What if you have no cards left in your deck? With a Lunatone in play yoiu cannot use the Power but if Lunatone is not in play then you can???
