Can Nocturne be played after using Stacked Deck when an opponent contests a battlefield you control?

Ruling: No, Nocturne cannot be played in this scenario because Stacked Deck does not draw cards - it only looks at cards from the top of your deck. Nocturne's ability specifically triggers when you look at cards from the top of your deck and don't draw them, but in this case you would need to actually see Nocturne during the look effect, not draw it.

Nuances:

• Stacked Deck does not resolve "at a battlefield" - it resolves on the stack
• Nocturne can be played to any battlefield you control when its trigger condition is met
• The key issue is that Stacked Deck's effect is looking at cards, not drawing them
