Card Rulings:Penalty Game!


 * "Penalty Game!" only requires your opponent to have 4 cards in hand when it is activated, not when it resolves. So your opponent can activate "Jar of Greed" to have 5 cards, or chain a Quick-Play Spell Card from his/her hand and have 3 cards, and "Penalty Game!" will still resolve.


 * If you choose the first effect, neither player can activate a card that would require the opponent to draw during their next Draw Phase, such as "Jar of Greed" or "Disturbance Strategy".


 * If the second effect of "Penalty Game!" is chosen, the opponent can still activate the effects of cards that are already face-up on the field, such as "Skull Lair" or "The Dragon's Bead".
