When playing Nocturne using his ability to play him for any power when looked at from deck, do you still have to pay the 1 Chaos Power cost?

Ruling: No, when you play Nocturne from your deck using his ability when looked at, you pay only one power of any color. If you play him from hand normally, you pay 1 Chaos Power and 4 Energy.

Nuances:

• The "any power" ability only applies when playing him from deck after looking at him
• Playing from hand uses his normal cost (1 Chaos Power and 4 Energy)
