Earthquake x 3
IF Altena is asleep when she is to act THEN Sleep Talk (Earthquake, Dragon Claw, Dragon Rush, Fire Fang) first and third instances, Sleep Talk (Sunny Day, Stealth Rock, Earthquake, Dragon Rush) second instance

IF Roserade is under successful P/E AND Stealth Rock is not set up on the opponent's side THEN Stealth Rock
